The World Trade Organization says world trade is on track to expand 2.4 percent this year, although there is “deep uncertainty” about economic and policy developments in the United States. The WTO says clarity is needed on President Donald Trump’s trade policies. The WTO pushed against trade protectionism in comments, as a spokesperson said: “We should see trade as part of the solution to economic difficulties, not part of the problem.” Trump has already removed the U.S. from the Trans-Pacific Partnership trade agreement that was worth more than an estimated $4 billion to U.S. agriculture. Trump also intends to renegotiate the North American Free Trade Agreement, which could cause tensions between the U.S. and Mexico and Canada. Mexico is the number one customer for U.S. corn and corn-based products.
