[photo collected] US President Joe Biden's China policy would be shaped on three key issues in the Pacific Ocean, viz - South China Sea, Taiwan, and Taiwan Strait and Japan and a system of alliances and partners, reported CNN. These three constitute the Pacific military flashpoints between the US and China. In the South China Sea region, China claims almost all of the 1.3 million square miles of the South China Sea. Since 2014 it has built up tiny reefs and sandbars into man-made artificial islands, fortified with missiles, runways and weapons systems -- antagonising governments with overlapping claims, including the Philippines, Vietnam, Malaysia, Indonesia, Brunei and Taiwan, reported CNN.
