  • This paper is to analyse conflict between the US and China over the South China Sea and Korea's responses. To this end the paper is composed of 6 chapters titled instruction; the current status of South China Sea sovereignty disputes; changes in US and Chinese maritime security strategies and the strategic values of the South China Sea; key issues and future prospects for US-China conflicts in the South China Sea; South Korea's security and diplomatic responses; and conclusion. The recent East Asian maritime security issue has evolved into a global issue of supremacy between the US and China, beyond conflicts over territorial disputes and demarcation among the countries in the region. China is pursuing offensive ocean policy to expand economic growth. The core of the maritime order that the United States intends to pursue is the freedom of navigation in the oceans and the maintenance of maritime access. China is making artificial islands in the South China Sea, claiming the sovereignty of these islands, building strategic bases in East Asia, and securing routes. The United States has developed several "Freedom of Navigation Operations" to neutralize the declaration of the territorial sea surrounding Chinese artificial islands. We can not be free from marine conflicts in the South China Sea and the East China Sea. Regarding the South China Sea dispute, it is expected that the strategic competition and conflict between the two countries will intensify due to China's failure to make concessions of core interests and adherence to the US compliance with international norms. In the midst of conflict over the South China Sea, we need a harmonious balance between our alliance security and economic diplomacy. We must continue our efforts to strengthen the ROK-US alliance but not to make China an enemy. Considering the significant impacts of the oceans on the survival and prosperity of the nation, we must continue to develop our interest in the oceans, appropriate investments and tactical strategies.

  • AThis paper measured real sea area for performance analysis according to distance from west sea and south sea of Korea. The performance of the underwater OFDM system was analyzed by comparing the performance of the West and South Seas by adjusting the number of data repetitive transmissions and the pilot symbol placement interval parameters based on the real-sea data measured from the distance and Data rate of the West and South Sea vessels. In conclusion, when comparing the performance of the South Sea at the Data rate and distance, the BER performance of the South Sea was similar at the 5 km South Sea and 1 km West Sea under the same conditions. Placement interval of pilot symbol at 10 km of South Sea and 3 km of West Sea is (𝚫f, 𝚫t) = (6, 3) and the number of times the PRB is (Rf, Rt) = (2, 1) repeated. We confirmed that we can send high data over long distances in the South Sea.
