TAIPEI, Taiwan For years, Taiwan has enjoyed solid bipartisan support in Washington a consensus that has only strengthened as China has increasingly threatened the self-governing island, which it claims as its own territory and has promised to reunify with the mainland.

In recent months, however, Donald Trumps rhetoric has left some experts questioning whether Taiwan could continue to rely on the U.S. if the former president is reelected to the White House, given his wariness of American commitments to foreign partners and his enthusiasm for strongmen like Chinese President Xi Jinping.

Taiwanese officials HuffPost heard from during a weeklong press delegation last week largely struck a diplomatic tone when asked about the upcoming U.S. election.

Deputy Foreign Affairs Minister Franois Chihchung Wu said Taiwan will be closely monitoring the election on Tuesday and expressed measured anxiety about what the outcome will mean for future relations between the two democratic countries.

Of course, we are very concerned by the presidential election of the U.S., because the U.S. is our most important ally, he told the group of visiting international reporters, responding to a question from Brad Dress as The Hill.

Wu added that Taiwans concern boils down to uncertainty and said the island remains hopeful that whoever is elected on Nov. 5 will continue supporting its capital, Taipei.

Polls show Vice President Kamala Harris and Trump in a neck-and-neck race for the Oval Office. The vote comes as observers worry a flashpoint is nearing for bubbling tensions between communist-led China and Taiwan, officially known as the Republic of China.

Since establishing relations with China in 1979, America has maintained a one China policy that recognizes the Beijing government as the sole representative of China and acknowledges but does not endorse its claim to Taiwan.
