A group of 22 Senate Republicans has urged U.S. President Joe Biden not to make any concessions on Taiwan when he meets with his Chinese counterpart, Xi Jinping, on Wednesday.

"Few issues are more urgent than ensuring Taiwan has the capabilities and training it needs to deter Chinese aggression," said the statement spearheaded by Sen. Jim Risch (R-ID), the Senate Foreign Relations Committee's ranking member.

Biden and Xi are meeting in San Francisco for the first time in a year on the margins of the APEC leaders' summit. Biden said Tuesday that his main objective was to "get back on a normal course of corresponding" with China, with a view to preventing a crisis between their militaries.

The ongoing tensions in the Taiwan Strait are among the top issues Biden is expected to discuss with Xi, who is visiting the United States for the first time in six years.

China effectively broke off lines of communication with the Pentagon and other government departments after former House Speaker Nancy Pelosi's (D-CA) visit to Taiwan in August last year. White House and Defense Department officials have expressed a desire to restore dialogue in order to keep potential misunderstandings and miscalculations from escalating into disaster.
