Asian markets drifted higher on Tuesday as a landmark meeting between U.S. President Donald Trump and North Korean leader Kim Jong Un began in Singapore and ahead of central bank meetings in the coming days.
Japan's Nikkei 225 rose 0.58 percent, but was off a session high touched earlier in the morning as the Japanese currency inched off its intraday low.
Other markets in the region were little changed. South Korea's Kospi rose 0.25 percent after trading both above and below the flat line, and Australia's S&P/ASX 200 tacked on 0.24 percent.
Over in greater China markets, Hong Kong's Hang Seng Index added 0.16 percent, with the energy and service sectors leading gains. On the mainland, the Shanghai composite gained 0.15 percent.
MSCI's index of shares in Asia Pacific excluding Japan edged up by 0.1 percent in Asia morning trade.
Trump-Kim meeting underway
The high-profile Trump-Kim summit â€” the first meeting between sitting leaders of both countries â€” is currently underway, but analysts have said they expect little direct impact on the markets.
Trump and Kim will likely discuss future bilateral ties, although no major breakthroughs are expected from the meeting.
"Aside from the photo opportunities that today brings, from a financial markets perspective, today ranks as a 'meh,'" Robert Carnell, Asia Pacific head of research at ING, said in a morning note. He added that developments in the trade arena "is a far, far bigger existential global threat."
Still, the dollar was firmer on Tuesday despite the lack of certainty over what might be achieved. The greenback edged up 0.3 percent against the safe-haven yen to trade at 110.35 at 9:13 a.m. HK/SIN as the meeting began. The dollar had earlier firmed as much as 110.49.
The dollar index, which tracks the U.S. currency against a basket of peers, also strengthened to 93.786.
Markets' overall positive tone came despite that uncertainty in anticipation of several key events expected this week.
"[The risk-on tone] may have been a function of low volumes ahead of the Federal Reserve and European Central Bank this week, as asset allocators are unlikely to make strategic investment decisions until those events and the Singapore summit are out of the way," ANZ analysts said in a morning note.
Ahead, the Fed begins its two-day policy meeting on Tuesday, with markets expecting a quarter-point interest rate hike announcement on Wednesday. The ECB and Bank of Japan hold meetings in the second half of the week.
U.S. stocks finished the last session in positive territory despite recent trade concerns after last week's tense G-7 summit, which Trump had attended before arriving in Singapore on Sunday. Trump had withdrawn his support to endorse the joint G-7 communique and criticized Canadian Prime Minister Justin Trudeau.
Trump continued to fan trade tensions in a series of tweets critical of traditional allies of the U.S. on Monday during Asia business hours.
