China's increasing focus on its own security and intensifying rivalry with the United States threatens to turn its re-engagement with the world after years of COVID curbs into a new era of isolation from the West, analysts say.

Since casting off pandemic controls that effectively shut its borders since 2020, Beijing has in recent months embarked on a series of seemingly contradictory diplomatic and business steps that have left many observers questioning its motives.

These have included: promoting peace in Ukraine while holding talks with the aggressor Russia, rolling out the red carpet to Western leaders while escalating tensions over democratic Taiwan, and wooing foreign CEOs while taking measures seen as stifling China's business environment.
