Taiwan does not have any treaties with the United States, because the United States does not recognize Taiwan as a country, or have normal diplomatic relations with Taiwan, ever since the Taiwan Relations Act of 1979. The US _did_ have a mutual defense treaty with Taiwan, but it was terminated by the Taiwan Relations Act after the US initiated diplomatic relations with the People's Republic of China on Jan 1st, 1979.
