HONG KONG — Asian stocks advanced Friday led by big gains in Japan after U.S. President Donald Trump promised that he would soon cut taxes for businesses. Japan's benchmark Nikkei 225 index surged 2.3 percent as the yen weakened against the dollar, lifting shares of exporters.

TRUMP ON TAXES: In a meeting with airline and airport executives, Trump vowed to roll back government regulations and said he would announce a plan in the next three weeks to reduce taxes for businesses. The comments were short on details, but encouraged investors who have been waiting to see how Trump follows through on campaign promises to boost economic growth.

THE QUOTE: "We face a nice pop in Asian equities on open thanks largely to Mr. Trump," said Chris Weston of IG Markets in Melbourne. "The market loves the idea of tax reform. It has corporate tax cuts in its sights and if Trump can push that along with a more simplified personal tax regime the U.S. and global equities will find buyers."
