This is what Donald Trump understands. This is the trade deficit. We run a trade deficit of close to $800 billion a year.

The really big problem with China is that there are the unfair trade practices, like currency manipulation, illegal export subsidies and the theft of intellectual property, but then there's also things that the WTO doesn't cover that it should, which is the use of sweat shops and pollution havens.

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.

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.

This is what Donald Trump understands. This is the trade deficit. We run a trade deficit of close to $800 billion a year.
