Leaders of the European Union and Japan have launched an alliance aimed at boosting economic cooperation, defending free trade and countering unfair trade practices as the two sides face growing challenges from the United States and China.

The European Union and the U.S. are moving toward a trade deal that could include a 15% U.S. baseline tariff on EU goods and possible exemptions, two European diplomats said on Wednesday, potentially moving President Donald Trump closer to another major trade agreement on the heels of the one he just unveiled with Japan.

U.S. President Donald Trump has now set his sights on trade negotiations with the European Union, after announcing a framework agreement with Japan. "We have Europe coming in tomorrow, and the next day, we have some other ones coming in," Trump said late on Tuesday, without specifying details.
