China Rim

See also: Asia–Pacific, Indo-Pacific, and Necklace of Diamonds

The region of all countries bordering China is sometimes referred to by scholars as the China Rim,^[3][4][5] or simply as China's periphery (Chinese: 中国周边).^[6] The China Rim plays a significant role in competition between other countries and China, as is the case with America's China Containment Policy.^[7] Significant competition took place between America and China in the region after the middle of the 20th century.^[8][9][10] Currently, a greater level of scrutiny and competition are happening around the maritime portion of the rim (particularly Taiwan and Maritime Southeast Asia).^[11]
