NATHANA REBOUCAS-UNSPLASH

HUAWEI Technologies Co. and China Mobile Ltd. have built a 3,000-kilometer(1,860-mile) internet network linking Beijing to the south, which the country is touting as its latest technological breakthrough.

The two firms teamed up with Tsinghua University and research provider Cernet.com Corp. to build what they claim is the world鈥檚 first internet network to achieve a 鈥渟table and reliable鈥 bandwidth of 1.2 terabits per second, several times faster than typical speeds around the world. Trials began July 31 and it鈥檚 since passed various tests verifying that milestone, the university said in a statement.

Tsinghua, Chinese President Xi Jinping鈥檚 alma mater, is plugging the project as an industry-first built entirely on homegrown technology, and credits Huawei prominently in its statement. The Chinese firm in August made waves when it released a 5G smartphone with a sophisticated made-in-China processor, inspiring celebration in Chinese state and social media. That event also spurred debate in Washington about whether the Biden administration has gone far enough in attempts to contain Chinese technological achievement.

The network 鈥渋s operated based on China鈥檚 domestically-owned key technologies,鈥 the official Xinhua News Agency said in a report carried on Tsinghua鈥檚 website.

Bloomberg News hasn鈥檛 verified the authenticity of those claims. In February, Nokia 鈥 Huawei鈥檚 global rival 鈥 announced it鈥檚 achieved 1.2 terabits a second over what it called 鈥渕etro distances鈥 of about 118 kilometers on an optical network in Europe. 鈥 Bloomberg
