China has announced a series of new fines on big tech companies, including Alibaba, Didi Chuxing and Tencent, for irregularities related to merger or acquisition agreements over the past decade.

In a series of statements issued on Wednesday night, the State Administration for Market Regulation (SAMR) revealed up to 22 fines of 500,000 yuan ($77,240) each, a very small amount compared to the multibillion-dollar revenues of the affected companies but the maximum allowed by China's anti-monopoly law for such irregularities.

Out of the 22 fines, eight have been imposed on subsidiaries of Didi, referred to as the "Uber of China", six on e-commerce giant Alibaba, and five on multinational technology conglomerate Tencent, developer of the popular social media platform, WeChat.

The regulator penalizes these companies for not adequately informing the authorities to approve the acquisition of parts of other companies or the establishment of joint ventures with their partners, although in some cases these operations occurred before 2018, the year in which the SAMR was established.
