China Property Rallies
Real-estate developers saw extended gains with Lvjing Real Estate jumped 2.5 percent after April's new home prices rose at their fastest pace in two years.
"We don't think the authorities will be satisfied until there is no evidence of overheated prices in any of the 70 cities. Housing is prone to overheating but boom-bust is not the natural state of the market," said Tim Condon, head of research for Asia at ING Financial Markets in a note.
Meanwhile, a 10 percent gain in dairy producer China Mengniu Dairy supported the rally in Hong Kong shares on news of a joint venture by Danone Group.

Investors are awaiting Tuesday's minutes from the latest Reserve Bank of Australia (RBA) gathering for signs of further stimulus from the central bank.

Kospi Down 0.2%
Rising tensions on the Korean peninsula over the weekend added some pressure to Seoul's benchmark index. Pyongyang fired off four short-range missiles for two days in a row despite international condemnation.
The Kospi moved further away from a six-week high of 1,991, weighed down by a 10 percent slump in STX Corporation. Shares tanked after the holding company of troubled STX shipbuilding group received a $271 million cash injection last week.
