The dollar rose against the yen on Monday on relief that U.S. President Donald Trump set aside tough campaign rhetoric over security and jobs in a smooth meeting with Japanese Prime Minister Shinzo Abe, with no mention of currency policy.
Asian stocks ticked up, helped by renewed optimism over Trump's tax reform plans, generally upbeat global economic data and Trump's change of tack to agree to honour the "one China" policy.
"The global economy seems fairly sound now, compared to last year, as China is supporting its economy through fiscal measures. The downside risk in the U.S. economy is small due to Trump's policies," Masayuki Kichikawa, chief macro strategist at Sumitomo Mitsui Asset Management.
The dollar rose as much as 0.9 percent against the yen to 114.17 yen, extending its rebound from 111.59 yen touched last Tuesday, which was its lowest level in 10 weeks.
A senior Japanese government spokesman said Abe and Trump did not discuss currency issues and that Trump did not request a bilateral trade deal.
The official told reporters that a U.S.-Japan economic dialogue will be led by Japanese Deputy Prime Minister Taro Aso and Vice President Mike Pence. It will address fiscal and monetary policies as well as infrastructure projects and trade.
"We can expect a realistic approach as the dialogue will be led by Pence and Aso. It is reassuring that an unpredictable Trump is not in it," said Yasunobu Katsuki, senior primary analyst at Mizuho Securities.

Comments from Trump on Thursday that he plans to announce the most ambitious tax reform plan since the Reagan era in the next few weeks rekindled hopes for big tax cuts.
