<span style="color: #222222;">China on Tuesday made two big announcements for its tech sector in moves set to further tighten Beijing's grip over its extensive technology sector. The Cyberspace Administration of China (CAC) said it implement new rules that will boost oversight over how its platform companies make plans to list abroad or use recommendation algorithms.<br />''<br />''The CAC said it would enforce new rules from February 15 that would require platform companies with data for more than 1 million users to undergo a security review before listing their shares overseas. The CAC last year said, the new listing rule would put a focus on the risks of data being affected, controlled or manipulated by foreign governments after overseas listings.<br />''<br />''The China Securities Regulatory Commission (CSRC) said on Dec. 24 it would require companies wishing to list overseas to submit filings to the agency first for registration, under a system that also involves close coordination among various regulatory bodies.<br />''<br />''In a separate statement, the CAC also said it would implement new rules to rein in algorithms used on apps to recommend what consumers would like to read, watch, play and buy online, marking Beijing's latest effort to bring the country's Big Tech sector firmly in line with state policies. The algorithm is the main basis for the business models of internet giants including Alibaba, Tencent and ByteDance. Under new rules published on Tuesday and taking effect March 1, consumers will have the right to switch off algorithmic recommendations on apps and see or the keywords the algorithms use to target them.<br />''<br />''The new regulation, according to a statement from the CAC on Tuesday, seeks to address "algorithmic discrimination", which has led to differentiated pricing of products and services. Certain internet platforms have been charging consumers extra fees based on data about these users' spending habits.<br />''The CAC said the new regulation also aims to put a stop to so-called content intoxication like keeping users constantly engaged with a near-endless amount of content tailored to their tastes and interests. In addition, the algorithms used on many video games are designed to keep encouraging players to spend more time and money on them.<br />''<br />''The algorithm regulation is expected to help authorities clamp down on information recommendations, which have the potential of "shaping public opinion" or "social mobilisation", according to the CAC. In a related development, Online news providers will be required to get a license for their services.<br />''<br />''They are also specifically prohibited from publishing information that is not from the government's list of approved news sources. In October last year, Beijing released its white-list of 1,358 news outlets.</span><br />
