Republican presidential candidate Donald Trump said he would impose additional tariffs on China if China were to "go into Taiwan," the Wall Street Journal reported.

"I would say: If you go into Taiwan, I'm sorry to do this, I'm going to tax you, at 150% to 200%," the former U.S. president was quoted as saying in an interview with the WSJ published on Friday evening.

Trump, asked if he would use military force against a blockade on Taiwan by China, said it would not come to that because Chinese President Xi Jinping respected him.
