The 马六甲海峡 (Strait of Malacca) is a narrow waterway located between the Malay Peninsula and the Indonesian island of Sumatra. It connects the 南海 (South China Sea) to the 印度洋 (Indian Ocean) and is one of the busiest shipping routes in the world. The strait is approximately 805 kilometers long and varies in width, making it a crucial passage for international trade. Historically, the 马六甲海峡 has been significant for maritime navigation and commerce. It serves as a vital link for ships traveling between 东亚 (East Asia) and 欧洲 (Europe), facilitating the transport of goods such as oil, natural gas, and consumer products. The strait's strategic importance has also made it a focal point for geopolitical interests in the region.
