Dole told the Journal that the law firm he is affiliated with does work with the Taipei Economic and Cultural Representative Office in the U.S.
“It’s fair to say that we may have had some influence,” he said.

For several decades, the U.S. has followed the "One China" policy that doesn't acknowledge Taiwan as a nation, but instead goes along with China's view that Taiwan is a province that broke away.
President Jimmy Carter formally declared the communist People's Republic of China the sole government of China in 1979, which ended formal U.S. diplomatic relations with the nationalist government on Taiwan.
