The Biden administration will send an unofficial delegation comprised of former senior officials to Taiwan shortly after the self-governed island holds an election for a new president this weekend, a move that could upset Beijing in an already-fragile bilateral relationship.

A senior administration official confirmed the plan on Wednesday without offering more details but said such a face-to-face meeting was the “most effective way” to engage the new Taiwanese government and convey U.S. policy in the region.

The official, briefing reporters on condition of anonymity to discuss sensitive plans, said the administration believed the move would contribute to peace and stability in the region.

Beijing claims Taiwan to be part of Chinese territory and vows to unify with it eventually.
