(Bloomberg) -- China is set to pass a new law that would restrict sensitive exports vital to national security, expanding its toolkit of policy options as competition grows with the U.S. over access to technologies that will drive the modern economy.China’s top legislative body, the National People’s Congress Standing Committee, is expected to adopt the measure in a session that concludes on Saturday. The Export Control Law primarily aims to protect China’s national security by regulating the export of sensitive materials and technologies that appear on a control list. It would apply to all companies in China, including foreign-invested ones.The measure would add to Beijing’s regulatory arsenal, which also includes a tech export restriction catalog and an unreliable entity list. The law would also help put China on a similar footing to the U.S., which regularly uses export controls and licenses strategically against its adversaries.Mounting tensions between China and the U.S. have spilled over into the realm of technology. Big Chinese companies including Huawei Technologies Co., ByteDance Ltd.’s TikTok, Tencent Holdings Ltd.’s WeChat and Semiconductor Manufacturing International Corp. find themselves in Washington’s cross-hairs.“Chinese authorities may have learned a lesson from the U.S. and other countries,” said Qing Ren, a partner at Global Law Office in Beijing.A report carried by official Xinhua News Agency said the draft law stipulates that China could take reciprocal measures against a certain country or region that has “abused export control measures and damaged China’s national security and interests.”The official Legal Daily reported on Thursday that some legislators had suggested source codes, algorithms and technical documents be added as controlled items, and that China should set up some restrictions on exporting technologies on which Beijing has a competitive edge, such as 5G and quantum communications.Whether Beijing will allow the export of valuable Chinese technology is one of the biggest uncertainties hovering over the partial sale of TikTok to Oracle Corp. and American investors. China in August asserted the right to block the deal by adding speech recognition and recommendation technology -- the core of TikTok’s global popularity -- to a list of regulated exports.How Blacklisting ‘Entities’ Became a Trade War Weapon: QuickTakeThe existing control lists are much narrower than the one used by the U.S., staying limited to materials that could be used for nuclear, chemical or biological weapons, Ren said. If it’s expanded in the future “then more products or technologies will be subject to export control in China,” he said.The Chinese Ministry of Commerce partially updated its export control list in August, putting cutting-edge technologies such as recommendation algorithms and drones under Beijing’s watch.While the U.S. is generally ahead of China in most spheres, China controls critical aspects of technology in industries from wireless networking to unmanned aerial vehicles.Tech HeadwayAmerican officials have warned that Huawei -- the leader in next-generation wireless patents -- controls a 10th of worldwide essential 5G patents, and its deep involvement in international standards-setting could post a threat to U.S. national security. The company ranked among the top 10 recipients of U.S. patents in 2019 -- helping China become the fourth-biggest recipient of American patents, behind Japan and South Korea but ahead of Germany for the first time.Chinese companies have also made headway in dominating certain niches. Shenzhen-based SZ DJI Technology Co. controls something like three-quarters of the global consumer drones market. Display maker BOE Technology Group is aggressively filing patents in its bid to get into next-generation OLED screens for smartphones.And in artificial intelligence, companies from Alibaba Group Holding Ltd. to Tencent and upstarts like SenseTime Group Ltd. are taking advantage of unparalleled reserves of data to advance in areas such as facial recognition.How Huawei Landed at the Center of Global Tech Tussle: QuickTakeWhen approved, China’s law will be applied extra-territorially, taking a page from the U.S. Export Administration Regulations’ long-arm jurisdiction that Beijing has frequently criticized. Foreign Ministry officials have repeatedly accused Washington of stretching and abusing the concept of national security in justifying actions against Chinese companies.China is the biggest exporting country in the world and overseas sales provide jobs for millions of people, so it will be careful not to abuse the law, said Mei Xinyu, a researcher at a research group under China’s Commerce Ministry. “We highly value China’s image as a reliable supplier in the international market,” Mei said. “So we wouldn’t expand the scope of export control at will.”China’s Ministry of Commerce first published a draft of the legislation in June 2017. It went through two reviews by the NPC in December 2019 and at the end of June. When the draft bill was introduced for its first review, Minister of Commerce Zhong Shan explained to the national legislature that export control is a mechanism aimed at “honoring international obligations such as nonproliferation and safeguarding national security and developmental interests.”But in a draft reviewed in June, national security was given higher priority.“Threats to national security could come from various fields, including the economic field,” said Cui Fan, a professor of international trade at the University of International Business and Economics. “But we can’t confuse normal competition between companies with threats to economic security and national interests.”Why Trump Is Threatening Your Teen’s Favorite App: QuickTakeThe latest version further clarifies the scope of controlled items and punishment measures for violations. Government departments overseeing export control should publish export control guidance in a timely manner, a spokesperson of the NPC’s legislative affairs commission said on Monday, without elaborating.Foreign companies need not fear the law since it applied equally to all companies operating in China, according to Ren from Global Law Office. Still, he said, foreign-invested companies should be careful if their activities involve the export of technologies.“Chinese employees maybe are not allowed to release the controlled technologies to their foreign colleagues,” Ren said. “This depends on the very specific circumstances of the each individual company. But it could happen.”(Updates with more detail on current control list in tenth paragraph.)For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.©2020 Bloomberg L.P.
