If you've been to China, you know there are over 100 cities in China, and the pollution levels are just horrific - 60,000 people a year die in Chinese factories and facilities, because they don't have any safety regulations. It's a carnage; it's Dickensian.

In my movie, "Death By China," it shows Bill Clinton in 2000 promising that when China got into the World Trade Organization we would be making products here and selling them there, and life would be great. Just the opposite has happened. And here's why this has been so devastating - China went into the World Trade Organization and agreed to play by certain rules. Instead, it's violated these rules. For 15 years, it continues to illegally subsidize its exports.

The defining moment in American economic history is when Bill Clinton lobbied to get China into the World Trade Organization. It was the worst political and economic mistake in American history in the last 100 years. China went into the World Trade Organization and agreed to play by certain rules. Instead, they are illegally subsidizing their exports, manipulating their currency, stealing all of our intellectual property, using sweatshops, using pollution havens. What happens is, our businesses and workers are playing that game with two hands tied behind their back.

From 1947 to 2001, the American economy grew annually at a rate of 3.5 percent. After China got into the World Trade Organization, got access to our markets and flooded our markets with its illegally subsidized exports, we grew at a rate of 1.8 percent from 2002 to 2015. That's almost cut in half.

When we run these big trade deficits and send our jobs offshore, we hold our wages down and our income down. That feeds right back into the biggest part of this whole equation, consumption. This drags GDP down as well.

Donald Trump is not a protectionist. If he imposes tariffs on China or any other country that cheats, all he wants to do is defend America against unfair trade practices.

China are running trade deficits with the rest of the world. If you look at the U.S. trade deficit, it's close to $800 billion trade in goods. Half of that is with China, so it's a big part of the problem. And the problem with China, as opposed to, say, Canada, is that China cheats.
