Republican presidential front-runner Donald Trump has said he is not angry at countries like China, India, Vietnam and  Japan for taking away jobs from United States, but at the "incompetent" American leadership.

The New York billionaire said during his campaign rally in a town of Indiana,"I'm not angry at China. I'm not angry at Mexico. I'm not angry at India or Vietnam, which is hot as a pistol right now, taking a lot of stuff away from us."

"I'm not angry at Japan. They send cars over by the million. We give them practically nothing. You talk about a trade unbalance. They're up here. We're down like below that stage. It's trade imbalance. I'm not angry at any of them.”

"I'm angry at our leaders for being grossly incompetent and not knowing. Right?," the real estate mogul said in his characteristic style amidst a big applause from the audience.”

"And not knowing what they're doing, because there's no reason for it," Trump added.
