SHANGHAI, Dec 27 (Reuters) - Hong Kong stocks rebounded as the market reopened on Wednesday, led by a rally in gaming firms after regulators vowed to make improvements to proposed rules that had sent stocks in gaming companies plunging.

Mainland China shares edged up, with semiconductor firms leading the gains.

** Hong Kong's Hang Seng Index rose 1.5%, and the Hang Seng China Enterprises Index climbed 1.8% by the midday recess.

** The blue-chip CSI 300 Index and the Shanghai Composite Index added 0.4% each.

** The broad Asian stocks also rose, tracking a Wall Street rally as investors latched on to the year-end optimism driven by expectations the Federal Reserve could begin cutting rates as early as next March.

** Tech giants listed in Hong Kong climbed 2.3%, led by a 5.9% rebound in Tencent Holdings and a 10.3% jump in NetEase, following sharp declines in the two gaming giants in the previous session, as China's new rules to curb spending on video games dented sentiment.

** To soothe sentiment, China's video game regulator - the National Press and Publication Administration - has struck a more conciliatory tone, saying it would improve the rules by "earnestly studying" public views. It then approved new licenses for 105 domestic online games for December - more than the monthly average.

** China's Anime Comic Game Index, covering smaller game makers listed in mainland markets, edged up 0.4%, following a 15% slide over the previous three sessions.

** China's November industrial profits posted double-digit gains as overall manufacturing improved, although soft demand continued to constrain business growth expectations.

** In China markets, shares in semiconductors jumped 2%, while energy companies and securities brokers advanced roughly 1.2% each. (Reporting by Shanghai Newsroom; Editing by Mrigank Dhaniwala)
