The PRC is trying to expand into Indonesia's exclusive economic zone.
The PRC received a bloody nose when it tried to invade Vietnam some decades ago. And of course there is the Indian border along with military support provided to India's adversaries.
The USSR once pinned the PRC in on other borders and they nearly came to blows. The demise of Russia under Putinist stupidity will likely result in an expansion of the PRC borders and influence accross former Soviet republics.
