The benchmark Hang Seng Index finished up 1.73 percent at 22,685.22, breaching the 200-day moving average for the first time in three days. The China Enterprises Index climbed 1.75 percent.
The Shanghai Composite Index edged up 0.08 percent.
HIGHLIGHTS:
Foxconn International Holdings Ltd led gains, up 5.2 percent, on what analysts said was speculative buying ahead of its earnings announcement on March 30. A 12 percent slide last week made Foxconn technically oversold, with its relative strength index (RSI) hitting the lowest-ever level of 9.9 last Friday. A reading below 30 suggests a stock is oversold.
China energy stocks largely benefited as Brent climbed 1.5 percent on Monday towards $116 per barrel after Western forces launched a military campaign against Libya, stoking fears that violence will intensify in North Africa and the Middle East, source of more than a third of the world's oil.
CNOOC Ltd gained 3.6 percent, while Petrochina Co Ltd also boosted by a record quarterly profit announced last week, advanced 3.3 percent. But China Resources Power Holding Co Ltd lost a further 1.4 percent after it announced a 7.8 percent fall in net 2010 profit last week.
PCCW Ltd , chaired by media tycoon Richard Li, climbed more than 4.6 percent on news the company is studying a plan to spin off its telecommunications operations to form Hong Kong's first listed business trust as the company struggles to maintain margins in a highly competitive market.
Property counters continued their bullish trend from last week, with China Overseas Land & Investment Ltd , the country's largest developer by market value, up 3.83 percent at a five week high. China Resources Land Ltd finished up 3.9 percent and Henderson Land Development Co Ltd gained 2.3 percent.
