By Jun Ebias and Claire Zhang
HONG KONG/SHANGHAI, Feb 2 Shares in China and Hong Kong were up in a cautious session on Tuesday, with metals issues up on rising commodity prices, while Chinese banks succumbed to profit-taking.
Hong Kong shares gave up earlier gains to close up 0.22 percent at midday, but turnover remained low, suggesting that most investors remained on the sidelines, worried that China may take more steps to rein in liquidity and curb bank lending.
Sentiment remained cautious, with the Shanghai market still under pressure from heavy new share supplies.
A major new listing fell below its IPO price on its first day of trade -- a rarity in the mainland market -- for the second time in less than a week.

Gaining Shanghai A shares outnumbered losers by 658 to 230, while turnover dipped to 54 billion yuan ($7.9 billion) from Monday morning's 56 billion yuan as trading wound down ahead of a week-long holiday to celebrate the Lunar New Year, which this year falls on Feb. 14.
Shandong Gold (600547.SS) jumped 6.89 percent to 67.47 yuan after gold prices posted their biggest daily gain in three months overnight, boosted by an oil rally. Jiangxi Copper (600362.SS) climbed 3.74 percent to 34.09 yuan on rising metals prices.
In Hong Kong, Real Gold (0246.HK) rose 6.85 percent, while Jiangxi Copper (0358.HK) was up 2.57 percent.
"The index is being lifted by overseas markets today, but the rebound is weak," said Zhang Gang, strategist at Central Securities in Shanghai. "IPOs are still coming at too fast a pace and there are too many of them on the horizon. The market is still suffering from liquidity pressures, but after the recent sell off the index is expected to hold stable before the Lunar New Year."
Tuesday brought additional news on new share supplies and an official clampdown on liquidity that is weighing on the market.
