Regional stocks were mostly higher on Monday while oil dipped ahead of talks between US President Donald Trump, Ukrainian President Volodymyr Zelensky, and European leaders in Washington.

In Tokyo, the Nikkei share average extended their gains in early trading from last week to hit a record high, tracking the Dow Jones' higher finish on Friday, as a weaker yen boosted automakers' stocks.

Trump met Russian President Vladimir Putin in Alaska on Friday, but the summit failed to yield any breakthrough on a ceasefire in Ukraine.

Zelensky, who will be joined in Washington by European leaders, however called a US offer of security guarantees to Ukraine "historic".

"Trump and Putin walked away without a ceasefire, without even the illusion of one," said Stephen Innes at SPI Asset Management.

"What they did offer was theatre: enough 'progress' for Trump to declare victory and quietly holster his double-barrelled threat – tariffs on Beijing for buying Russian barrels and sanctions on Moscow's crude," Innes said. (Agencies/Xinhua)
