Asian Tech Press (Jan 5) -- China's top market regulator said Wednesday it has fined units of Chinese e-commerce company Alibaba (9988.HK), computer company Tencent (0700.HK), video sharing website Bilibili Inc. (BILI) and online retailer JD.com Inc. for failing to properly report about a dozen transactions.

According to several announcements made on Wednesday, China's State Administration for Market Regulation (SAMR) penalised the companies 500,000 yuan ($78,474) for each unreported transaction, which is the highest penalty under the country's 2008 antitrust law.

These 4 penalised companies did not immediately respond to requests for comment. And the penalties come against the background of China's regulatory crackdown on a range of industries, of which the technology sector is a prime target.
