TOKYO (Reuters) - U.S. stock futures rose on Monday on signs that the United States and North Korea are still working towards holding a summit next month, while oil prices extended losses on expectations of more supply from major producers.
The euro edged up from a 6-1/2-month low but is seen vulnerable after efforts to form a coalition government in Italy, the currency bloc's third-biggest economy, collapsed over the weekend.
U.S. S&P500 mini futures rose 0.3 percent in early Asian trade, but market holidays in the world's two biggest financial centres -- London and New York -- could make trading slow and illiquid for the day.
Japan's Nikkei gained 0.3 percent in early trade, while South Korea's Kospi rose 0.5 percent, buoyed by stocks which are seen as benefiting from a further thawing in tensions with Pyongyang.
But markets elsewhere in Asia appeared little fazed by the latest North Korean news after a week of conflicting signals from Washington. MSCI's broadest index of Asia-Pacific shares outside Japan was flat.

Oil prices extended their decline since last Tuesday on growing expectations that major oil producers may ease their 17-month-old production cuts.
A return to the oil production levels that were in place in October 2016, the baseline for the current deal to cut output, is one of the options for easing curbs, Russia's energy minister said on Saturday.
His comments came after the energy ministers of Russia and Saudi Arabia met to review the terms of a global oil supply, ahead of a key OPEC meeting in Vienna next month.

"If the Italian debt prices fall further, people will have to do more hedging, say by selling the euro and so on. The issue will be the biggest focus for markets this week,"
