Chinese retailer Suning appointed a new chairman, according to a Friday filing to the Shenzhen Stock Exchange. Huang Mingduan, the former head of Alibaba-owned supermarket operator Gaoxin Retail, replaces Suning founder Zhang Jindong. Alibaba holds a 20% stake in Suning after participating in a state-led $1.36 billion bailout. The appointment signals that Alibaba is taking a front seat in the daily operation of its former rival.
