WASHINGTON, April 28 (Reuters) - A proposed trade deal between Canada and the European Union puts pressure on the United States to begin thinking about its own trade pact with Europe, U.S. manufacturers said on Tuesday.

"The EU already has a free trade agreement with Mexico. Now they're negotiating one with Canada and that leaves us out," Frank Vargo, vice president for international economic affairs at the National Association of Manufacturers, told reporters.

European Union foreign ministers agreed on Monday to launch talks with Canada on a deal expected to generate about $27 billion in annual economic gains by cutting trade barriers.

The United States has had a free trade pact with Canada since 1989, which was folded into the North American Free Trade Agreement when Mexico joined the trade pact.

The 27 countries of the EU are as a whole the United States' largest export market, while Canada is the United States' largest single trading partner.
