China intends to participate in the Russian Arctic Submarine Route Project
The Russian Federal Ministry of Communications and Mass Media reported that China is interested in the Arctic submarine mainline project. On June 28th, the Minister of Communications of the Republic of Nikiforov and Minister of Industry and Information Technology Miao Wei held talks.
China intends to participate in the Russian Arctic Submarine Route Project.
According to press releases, discussions at the conference included the construction of a submarine fiber trunk in the Arctic, a private mobile satellite communications system, and the digital economy in Russia, China, and other countries.
"The communications project is the focus of the discussion. The Chinese minister is very interested in developing the Arctic submarine trunk project in Russia." The press release stated that this project will establish a high-speed interconnection between Europe and Asia.
China also requires cooperation in the investigation of the construction of main lines. Chinese partners believe that the demand for this communication line will be very high.
“The key step in the transition to the digital economy is the exchange of experience and knowledge between countries. Russia and China are long-term strategic partners and friendly neighbors. Therefore, we undoubtedly have a large number of common ground in the digital economy.” Nikiforov said .
