GOP frontrunner Donald Trump has once again criticised the US trade deficit with China by using the term “rape” to describe it.

“We’re going to turn it around. And we have the cards, don’t forget it. We’re like the piggy bank that’s being robbed. We have the cards. We have a lot of power with China,” CNN quoted Trump as saying at his second rally in Fort Wayne, Indiana on Sunday.

“We can’t continue to allow China to rape our country, and that’s what they’re doing,” he added.

Trump has accused the country of manipulating its currency market several times earlier. In 2011, as he toured a defense manufacturer in New Hampshire, he claimed that “China is raping this country.” He also said it is “killing” the US on trade during Sunday’s rally.

The comments followed Trump’s endorsement of boxer Mike Tyson, who was convicted of rape in Indiana, The Hill reported. Trump’s GOP rival Ted Cruz and main competitor in the Indiana primary slammed him for touting Tyson as a “tough guy,” saying rapists are not tough guys but are weak and coward.

The billionaire said that he is not angry with Chinese authorities but the US politicians whom he accused were grossly incompetent.

In an interview with the New York Times in March, Trump said that while it’s easier for the Chinese companies to do business with the US, it is not the same the other way round.

“I do know my subject, and I do know that our country cannot continue to do what it’s doing,” he said. “It’s very hard for us to do business in China, it’s very easy for China to do business with us. Plus with us, there’s a tremendous tax that we pay when we go into China, whereas when China sells to us, there’s no tax. I mean, it’s a whole double standard.”
