China's JD.com CEO joins billionaire charity rush with $2.3 billion share pledge

JD.com founder and CEO Richard Liu will donate company shares worth about $2.34 billion to charity, the Chinese e-commerce giant said on Wednesday, adding to a list of similar philanthropic pledges from the country's top tech billionaires.

The move comes as China tightens scrutiny on its tech sector, including JD.com (JD) and rival Alibaba (BABA), as part of President Xi Jinping's "common prosperity" drive to ease inequality in the world's second-largest economy.
