China and Hong Kong stocks fell on Tuesday as investors locked in gains after a strong rally that was fuelled by record monthly foreign inflows, although analysts predict further upside ahead, citing growing signs of a post-COVID economic recovery. ** The correction could also be triggered by signs of an escalating Sino-U.S. tech war, and risk-off sentiment ahead of this week’s U.S. rate decision, Morgan Stanley said, adding the bank "would take the current opportunity to recommend buy-the-dip."
