China Turns Up Heat on Country's Tech Giants Joyce Huang TAIPEI - In recent weeks, Chinese regulators have cracked down on some of the country's biggest and most powerful technology companies, illustrating the immense market power of these companies, which has drawn concern from the government. On Monday, the State Administration for Market Regulation (SAMR), China's top market regulator, fined three of the country's largest technology companies, including e-commerce giant Alibaba Group and social-media juggernaut Tencent, for failing to disclose acquisitions of smaller competitors. Last month, China Securities Regulatory Commission halted the record initial public offering of Ant Group, one of China's dominant digital payment platforms backed by Alibaba. It then announced new draft rules targeting monopolistic practices on the country's digital platforms. .
