In Hong Kong, Jefferies chief global equity strategist Sean Darby said the positive sentiment towards Asian markets was the result of better-than-expected regional economic data and elevated liquidity levels.
"All of the global monetary policy indicators are flashing green right now. It is very loose and that should mean markets which have underperformed should do well," Darby told Reuters.
"The dollar has also been weaker over the past five days so emerging markets, led by China, normally do well on that back of that."
Most markets gained ground last week as a raft of economic data from June beat expectations, although the resurgence of coronavirus cases in the United States is clouding the future.

"Markets will have to climb a wall of worry in July as economic activity likely softens from the V-shaped recovery seen over recent months," said Robert Rennie, head of financial market strategy at Westpac. "We must remember, too, that U.S. and China relations are deteriorating noticeably."
