Long dominated by the United States, the Asia-Pacific region is grappling with an increasingly assertive China. Tensions are mounting around Taiwan and in the South China Sea, both in the air and on the water, with numerous incidents of late involving Chinese fighter planes, collisions between ships and reefs being turned into military outposts. Filmed in Japan, China, Taiwan and the Philippines, our documentary explores a new "cold war" pitting President Xi Jinping's authoritarian China against the US and its democratic allies in the region. This high-stakes conflict encompasses territorial, political, economic and ideological dimensions, as the threat of a third world war looms on the horizon.
