TAIPEI (Reuters) - Taiwan hopes to continue its close cooperation with the United States, the island’s de facto U.S. ambassador told Antony Blinken, a longtime confidant of President-elect Joe Biden, as Taiwan moves to shore up ties with the new administration.Claimed by China but democratically ruled, Taiwan enjoyed unprecedented support from President Donald Trump’s government, including stepped-up arms sales and visits of top officials to Taipei. Biden’s election has caused some unease in Taiwan. Hsiao Bi-khim, Taiwan’s representative in Washington and close to Taiwan President Tsai Ing-wen, spoke to Blinken by telephone to convey Taiwan’s congratulations to Biden, Hsiao said on Twitter on Saturday. “Appreciated bipartisan support for U.S. relations with Taiwan and hope to continue close cooperation with the U.S. in coming years,” she added. Tsai met Blinken in 2015 at the State Department when he was deputy secretary of state and she was the presidential candidate for Taiwan’s Democratic Progressive Party (DPP). On that trip, Tsai also became the first Taiwanese presidential candidate to visit the White House, meeting Evan Medeiros, President Barack Obama’s senior director for Asian Affairs. “It is thus clear that the government of the Democratic Party had a friendly attitude towards Taiwan,” Tsai said in a DPP-issued statement on Wednesday.
