US lawmakers from both major parties are calling on the Trump administration to reaffirm Washington’s support for Taiwan. Congressman John Moolenaar raised concerns in a letter to Secretary of State Marco Rubio about South Korea’s relationship with China, citing past comments by South Korean President Lee Jae-myung that downplayed his country's interests regarding security in the Taiwan Strait. Separately, Senator Roger Wicker met Taiwan’s representative to the US Alexander Yui on Tuesday. Following the meeting, Wicker said Washington must uphold its security commitments to Taiwan, underscoring continued congressional support for the country.
