SHANGHAI, April 26 (Reuters) - China stocks on Friday were on track to post their steepest weekly decline since October 2018, as investors feared the pace of Beijing’s supportive measures would drop amid signs of economic stabilization, and over Sino-U.S. trade concerns.

** The CSI300 index dropped 0.8 percent to 3,908.76 points at the end of the morning session, while the Shanghai Composite Index lost 0.8 percent to 3,099.36 points.

** For the week, both indexes lost more than 5 percent by midday, poised for their biggest weekly declines since Oct. 12, 2018.

** China’s central bank has no intent to tighten or relax monetary policy, a vice governor said on Thursday, as the market debates how much more support Beijing will give the economy after surprisingly resilient data was released last week.

** U.S. President Donald Trump said on Thursday he would soon host Chinese leader Xi Jinping at the White House, setting the stage for a possible agreement on trade between the world’s two largest economies.

** “Policy focus of the stock market has switched from proactively stimulating market vitality to curbing relatively heated sentiment, while there are expectations that liquidity would marginally tighten after an RRR cut did not happen as expected,” Northeast Securities said in report.

** Further progress in Sino-U.S. talks may be needed to lift the current weak market sentiment, as factors that had helped a robust stock market rally weakened to some extent, the brokerage added.

** In Hong Kong, the Hang Seng index added 0.1 percent to 29,583.67 points, while the Hong Kong China Enterprises Index gained 0.1 percent to 11,511.16 points.
