Most Asian markets gained Tuesday after losses the previous day as investors scooped up shares in banking, insurance and energy companies.
Analysts, though, warned the advance could be short-lived without clear guidance from Wall Street, and as anxiety over high oil prices and inflation persists.
"Investor sentiment is weak as the outlook for Wall Street is still uncertain," said Jackson Wong, investment manager at Tanrich Securities in Hong Kong.
The territory's blue-chip Hang Seng Index improved 0.6 percent to 24,282.04 after shedding nearly 1,500 points over the last week. Mainland stocks also climbed, with the Shanghai Composite Index up 0.3 percent to 3,375.4.
Japan's benchmark Nikkei 225 index also gained, rising 1.5 percent to 13,893.31 to recoup some of its 2 percent decline Monday.
