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.

Unfair trade practices drive up rents for younger people. They will drive up home prices for first-time home-buyers. So it's not just that we're losing jobs and factories. We're giving away our homes, our businesses, our companies, our technologies.

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.

The Donald Trump trade doctrine is this. America will trade with any country, so long as that deal meets these three criterion: You increase the GDP growth rate, you decrease the trade deficit, and you strengthen the manufacturing base.

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.

Donald Trump understands China influence. He's been talking about it since 1980. He understands it. The people that are on the other side of this, including his opponent, Hillary Clinton, have been part of every bad trade negotiation we've had since 1993.

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.
