Japan's $550 billion investment package agreed in this week's U.S. tariff deal could help finance a Taiwanese firm building semiconductor plants in the U.S., Japan's top trade negotiator Ryosei Akazawa said on Saturday.

White House Press Secretary Karoline Leavitt said, "Japan will now pay a 15% tariff versus the reciprocal rate of 24% that they initially had."

After months of fraught negotiations with the United States, Japan clinched a deal just days before punitive tariffs were scheduled to take effect.

Global stocks rose and the euro appreciated on Monday after a trade agreement between the United States and the EU lifted sentiment and provided some clarity in a week of key policy meetings by the Federal Reserve and the Bank of Japan.

Japan will invest $550 billion in the U.S. and allow the U.S. to tax Japanese goods sold in America at 15 percent.

Asian shares were mixed on Monday, with Japanese markets dipping despite overall optimism in the market after the  U.S. and EU reached a trade framework that includes a 15% tariff on most European goods.

TURNBERRY, Scotland, July 27 (Reuters) - The U.S. struck a framework trade agreement with the European Union on Sunday, imposing a 15% import tariff on most EU goods - half the threatened rate - and averting a bigger trade war between the two allies that account for almost a third of global trade.

"The biggest piece in the trade deal puzzle still remains, and the Chinese are unlikely to be as willing to fold."
