Former U.S. ambassador to the United Nations, Nikki Haley, on a visit to Taiwan Saturday said an isolationist policy isn’t “healthy” and called on the Republican Party to stand with her country’s allies, while still putting in good words for the party’s nominee, Donald Trump.

Haley, who ran against Trump for the Republican presidential nomination, told reporters in the capital, Taipei, that supporting U.S. allies, including Ukraine and Israel, is vital, and she underscored the importance of Taiwan — which Beijing claims as its territory, to be brought under control by force if necessary.

“I don’t think the isolationist approach is healthy. I think America can never sit in a bubble and think that we won’t be affected,” she said.
