An unofficial delegation sent by U.S. President Joe Biden visited Taiwan last week in a reaffirmation of the U.S. commitment to Taiwan’s security. The visit came a week after the United States announced new guidelines to “encourage U.S. government engagement with Taiwan that reflects our deepening unofficial relationship.”

The visit, along with the formal invitation of Taiwan’s top representative to Biden’s inauguration, followed by supportive policies and statements, has removed doubts that there could be cutbacks to the U.S. commitment to Taiwan in order to stabilize relations with Beijing.

Beijing, which views Taiwan as a breakaway province that should be put under PRC control, responded to the delegation’s visit with live military drills, its go-to response for incidents indicating closer Taiwan-U.S. relations. Live-fire exercises were conducted as a “strong countermeasure” to then-Health Secretary Alex Azar and then-Energy and Economy Undersecretary Keith Krach’s visits to Taiwan last year.
