China will further tighten its internet regulations with a pledge on Sunday to strengthen controls over search engines and online news portals, the South China Morning Post reports. President Xi has made China’s “cyber sovereignty” a top priority in his sweeping campaign to bolster security. The five-year cultural development and reform plan released by the party and State Council calls for a “perfecting” of laws and rules related to the internet. That includes a qualification system for people working in online news, according to the plan, carried by the official Xinhua news agency. Efforts will be made to improve the communication abilities of major news websites and online radio and TV stations and develop a system for communication on the mobile internet. Newspapers and magazine resources should also be merged or reorganized and news and publishing organizations with long-term financial and operational difficulties should be shut down or revamped, according to the outline.
