(Yicai Global) June 21 -- Market watchdogs in Zibo, Shandong province, are investigating China's app-for-everything Meituan-Dianping after meal delivery platform Ele.me accused it of stealing trade secrets.

The Market Supervision and Administration Bureau in Zhangdian district is probing the Hong Kong-listed firm, which runs China's biggest on-demand services app, but has no information to disclose at this time, China Economic Weekly reported today.

Meituan has not yet commented on the matter.

Meituan stands charged of stealing classified information from Ele.me, including lists of top-performing restaurants and their turnover and marketing employee salaries, according to the report.

Over 650 restaurants have quit their partnership with Ele.me since Meituan ruled that they had to choose to work with only one of the two providers, Ele.me told China Economic Weekly. Monthly sales of the restaurants in question tallied nearly CNY1.1 million (USD154,483).
