This research evaluates cooperation in transboundary rivers with special reference to the Great Mekong Subregion (GMS) program in the Mekong River Basin. The benefit sharing approach has been deployed as a theoretical framework to analyze the extent to which the riparian states have achieved cooperation. The river basin governance led by the Mekong River Commission since 1995 has not adequately performed due to non-participation of upstream countries and the lack of law enforcement mechanism. Since the late 1980s, China has undertaken hydropower development unilaterally, thereby triggering discomfort from the Lower Mekong countries. The GMS program has led China to strengthening economic ties with the downstream countries through hydropower development as investors and developers. The program has also supported the establishment of economic corridors, and removal of physical barriers and has paved the way for cooperation in other sectors, such as the environment, agriculture, tourism and energy. There are challenges for further cooperation, including the development gaps between China and the downstream countries, political tensions and environment impacts of hydropower dams in the river basin. The Mekong River Basin shows the possibility of cooperation through benefit sharing. Sharing benefits accrued from the river and beyond the river between China and the downstream countries have enhanced economic ties, thereby consolidating cooperation each another.

This paper examines the extent to which the Mekong River Basin countries have achieved socioeconomic benefits based on regional cooperation through the Greater Mekong Subregion (GMS) Program, focusing on hydropower development and the Mekong Power Grid. This study pays attention to the time period from 2012 to 2022. The benefit sharing approach is employed to evaluate the extent to which hydropower development and the Mekong Power Grid have contributed to the regional energy trade in the GMS program. The GMS program was launched by the Asian Development Bank (ADB) in 1992, and the Chinese provinces of Yunnan and Guangxi, Myanmar, Lao PDR, Thailand, Cambodia, and Vietnam have taken an active part in the program. The goals of the GMS program are to achieve poverty alleviation, economic development, and regional cooperation in various sectors, including energy, tourism, and transportation. The GMS Economic Cooperation Program Strategic Framework 2030 (GMS-2030), in 2021, provides a new framework for prosperous and sustainable development in the river basin. In the energy sector, the GMS program has been instrumental in facilitating hydropower development and creating the Mekong Power Grid with the Regional Grid Code (RGC), contributing to economic benefits and promoting regional trade of hydroelectricity. It is argued that the GMS program has enhanced regional cooperation between the riparian countries. Despite such achievements, the GMS program has faced challenges, including the gap of economic development between the riparian countries, socioeconomic and environmental concerns regarding hydropower development between the Upper and Lower Mekong countries, and geopolitical tensions from the US-China rivalry. These challenges should adequately be addressed within the program, which can guarantee the sustainability of the program for the river basin.

The Mekong River plays an extremely important role in Southeast Asia. Flowing through six countries, including China, Myanmar, Thailand, Laos PDR, Cambodia, and Vietnam, it is a site of great biological and ecological diversity and the habitat of numerous species of fish. It also supports a very large population that lives along the river basin. Therefore, much attention has been focused on the giant Mekong River Basin, particularly, its soil erosion and sedimentation problems. In fact, many methods have been used to calculate and simulate these problems. However, in the case of the Mekong River Basin, the available data is limited because of the extreme size of the area (about $795,000km^2$) and lack of equipment systems in the countries through which the Mekong River flows. In this study, we applied the Universal Soil Loss Equation (USLE) model in a GIS (Geographic Information System) framework to calculate the amount of soil erosion and sediment load during the selected period, from 1951 to 2007. The result points out dangerous areas, such as the Upper Mekong River Basin and 3S Basin (containing the Sekong, Sesan, and Srepok Rivers) that are suffering the serious consequences of soil erosion problems. Moreover, the present model is also useful for supporting river basin management in the implementation of sustainable management practices in the Mekong River Basin and other basins.

Rapid development in the upper reaches of the Mekong River, in the form of construction of large hydropower dams and reservoirs, large irrigation schemes, and rapid urban development, is putting water resources under stress. Many scientific reports have pointed out that cascade dams along the Mekong River lead to serious problems: not only hydrologically but also a decline of agricultural productivity due to a decrease of sediment supply in the Mekong Delta and a change of fish amount due to drastic change of the water environment. Cambodia and Vietnam, located in the lowest Mekong basin, are gravely affected by radical changes of hydrologic regime due to Mekong River developments. In particular, the Tonle Sap Lake in Cambodia is very sensitive to the flood cycle and flow variation of the Mekong River as well as inflow water quality from the Mekong River. More than 50% of Cambodian GDP depends on the primary industries such as agriculture, fishing, and forestry, and the Tonle Sap Lake plays an important role to support the national economy in Cambodia. In addition, Cambodian people usually take nourishment from the fish of Tonle Sap Lake. This research aims to assess the impacts of the Mekong river flow alternation on the hydrologic regime of the Mekong River - Tonle Sap Lake. We carried out rainfall-runoff-inundation simulation using CAESER-LISFLOOD for integrated water resource management in the Tonle Sap Basin and then analyze flood inundation variation of the Tonle Sap Lake due to the scenarios. Furthermore, the simulated inundation maps were compared to MODIS satellite images for model verification and hydrologic prediction.

Mekong River is the world's $10^{th}$ longest river and runs through China's Yunnan province, Burma, Thailand, Laos, Cambodia and Vietnam. And Tonle Sap Lake, the largest fresh water body in Southeast Asia and the heart of Mekong River system, covers an area $2,500-3,000Km^2$ in dry season and $10,000-16,000Km^2$ in wet season. As previously noted, the water within Sap river flows from the Mekong River to Tonle Sap Lake in flood season (between June and October) and backward to Mekong River in dry season. Recently the flow regime of Sap River might be significantly affected by the development of large dams in upstream region of Mekong River. This paper aims at basic study about the large scale flood inundation of Cambodia using by CAESAR-Lisflood. CAESAR-Lisflood is a geomorphologic / Landscape evolution model that combines the Lisflood-FP 2d hydrodynamic flow model (Bates et al, 2010) with the CAESAR geomorphic model to simulate flow hydrograph and erosion/deposition in river catchments and reaches over time scales from hours to 1000's of years. This model is based on the simplified full Saint-Venant Equation so that it can simulate the interacted flow of between Mekong River and Tonle Sap Lake especially focusing on the flow direction change of Sap River by season.

Cultural tourism is a form of tourism based on national cultural identity with the participation of the community to preserve and promote traditional cultural values. Cultural tourism is a trend of many countries in the world, it is suitable for the context in the Mekong Delta, Vietnam. Cultural tourism is very good for poverty reduction activities, so it is considered a direction of socio-economic development. The study's goal is to look at the factors that influence the development of cultural tourism in Vietnam's Mekong Delta. Survey findings from 1275 survey samples in the Mekong Delta, Vietnam, were used to compile the research data. Cronbach's Alpha reliability coefficient; exploratory factor analysis EFA; CFA confirmatory factor; SEM linear regression analysis are used to analyze and assess scales using SPSS 20, AMOS 24 software. According to the findings of the SEM model study, there are six factors that influence the development of cultural tourism in the Mekong Delta of Vietnam, including policy development tourism, infrastructure for tourism, human resources for tourism, tourism resources, geographic location, tourism products, and services. A discussion on administration is proposed to the development of cultural tourism in the Mekong Delta, Vietnam, based on the research findings.

The Mekong which is one of the world's most significant rivers plays an extremely important role to South East Asia. Lying across six riparian countries including China, Myanmar, Thailand, Laos, Cambodia and Vietnam and being a greatly biological and ecological diversity of fishes, the river supports a huge population who living along Mekong Basin River. Therefore, much attention has been focused on the giant Mekong Basin River, particularly, the soil erosion and sedimentation problems which rise critical impacts on irrigation, agriculture, navigation, fisheries and aquatic ecosystem. In fact, there have been many methods to calculate these problems; however, in the case of Mekong, the available data have significant limitations because of large area (about 795 00 km2) and a failure by management agencies to analyze and publish of developing countries in Mekong Basin River. As a result, the Universal Soil Loss Equation (USLE) model in a GIS (Geographic Information System) framework was applied in this study. The USLE factors contain the rainfall erosivity, soil erodibility, slope length, steepness, crop management and conservation practices which are represented by raster layers in GIS environment. In the final step, these factors were multiplied together to estimate the soil erosion rate in the study area by using spatial analyst tool in the ArcGIS 10.2 software. The spatial distribution of soil loss result will be used to support river basin management to find the subtainable management practices by showing the position and amount of soil erosion and sediment load in the dangerous areas during the selected 56- year period from 1952 to 2007.

The purpose of this study is to propose policy implications for improving the efficiency of corporate income tax management in Vietnam, by analyzing the study factors affecting the efficiency of corporate income tax management (evidence from Mekong Delta provinces, Vietnam). This study used a primary data collection method and collected data of 329 enterprises, including 49 joint-stock companies and 280 limited liability companies in 3 provinces - Tra Vinh province, Soc Trang province, and Ben Tre province. By using the binary regression method, the author discovered eight factors affecting the efficiency of corporate income tax management in the Mekong Delta region such as the time of operation of the enterprises, type of business, gender, business results, tax amount temporarily paid, compliance with tax policies, business scale, and tax debt ratio. From the above research results, the author proposes policies to support Tax Departments to improve the efficiency of corporate income tax management in the Mekong Delta region in the future. These policies include - for further promoting the tax policy propaganda to enterprises, tax authorities need to promptly handle tax arrears, enhance the inspection of tax debt enterprises, and focus on the business models, gender, age of the business owners, etc.
