China's two main Asian rivals, Japan and India, are seeking to mend their relations with it at a time of greater unpredictability in U.S. policy under President Donald Trump's administration. This development carries significant implications for geopolitics in the Indo-Pacific region and could strengthen Chinese President Xi Jinping's hand just when he has made himself China's absolute ruler by dismantling the collective-leadership system that Deng Xiaoping helped institutionalize.

Add to the picture Australia's hedging of its bets, despite a national furor there over China's interference in its internal affairs, and America's persistently cautious approach toward Beijing, seeking neither overt competition nor confrontation. All this gives Xi the strategic space to carry on with his muscular and revisionist foreign policy, reflected in China's growing military assertiveness in the vast Indo-Pacific region stretching from the Pacific to the Horn of Africa.

An intense pace of top-level meetings is setting the stage for improving Sino-Indian and Sino-Japanese relations. Chinese Premier Li Keqiang's Japan visit this week follows Indian Prime Minister Narendra Modi's April 27-28 "informal" summit meeting with Xi in Wuhan, China. The Wuhan summit came just days after Wang Yi became the first Chinese foreign minister to visit Japan for bilateral talks since 2009.
