Asian stocks were broadly higher after US President Donald Trump and North Korea's Kim Jong-Un met in Singapore for a historic summit.
In response to a question about whether they had reached an agreement on de-nuclearisation, Mr Trump said they will be "starting this process very quickly".
Japan's benchmark Nikkei 225 closed up 0.33% at 22,878.3 points. In China, Hong Kong's Hang Seng index was up 0.4% at 31,186.8.
In Australia, the benchmark S&P/ASX 200 index rose 0.15% to 6,054.4, while the South Korea's benchmark Kospi index was down 0.05% at 2,468.8.
Krystal Tan, Asia economist at Capital Economics, said the gains were limited due to a lack of detail. Indeed, Trump and Kim singed a "comprehensive" document - the contents of which are still unkown.
“Generally (the impact) is very small – probably because there is nothing really concrete coming out,” Tan said.
“At best, it’s a bit of a boost to sentiment,” she said, adding that the US Federal Reserve meeting would be a dominant factor for markets this week.
