U.S. President Donald Trump has made cultivating closer ties with Taiwan a critical part of his efforts to counter China’s rising influence. He has significantly increased weapons sales to Taiwan’s military, vowed to step up economic cooperation, and generally bolstered relations with the self-ruled democratic island — even in his waning days.

His successor, President-elect Joe Biden, will most likely continue on a similar path, albeit without Trump’s characteristic pugnacity.

As concerns grow about China’s increasingly aggressive behavior on the global stage, Biden will face pressure from Democrats and Republicans to strengthen ties with Taiwan, which Beijing considers part of its territory.
