Behind the Sino-US submarine cable competition: opportunities and challenges for Chinese companies


한어Русский языкEnglishFrançaisIndonesianSanskrit日本語DeutschPortuguêsΕλληνικάespañolItalianoSuomalainenLatina

From a technical perspective, submarine optical cables are important channels for information transmission, and their construction and operation involve many advanced technologies. China has made significant progress in related technical fields and has the strength to participate in international competition. However, the United States, for various reasons, has tried to restrict the participation of Chinese companies. This is not only a violation of the principle of fair competition, but also has an adverse impact on the development of the global communications industry.

From an economic perspective, the construction and operation of submarine optical cables can bring huge economic benefits. The participation of Chinese companies is expected to reduce costs, improve efficiency, and bring more benefits to all parties. However, the restrictions imposed by the United States may lead to higher project costs and lower efficiency, which will ultimately affect the development of the entire industry.

On the political level, the dispute over submarine optical cables between China and the United States also reflects the political game between the two countries. The United States uses it as one of the means to suppress China, trying to maintain its leading position in the communications field and safeguard its hegemony. However, this approach is not only not conducive to the improvement of relations between the two countries, but also not conducive to the healthy development of the global communications industry.

In addition, from the perspective of national security, submarine cables carry a large amount of sensitive information, and countries' concerns about their own information security are understandable. However, the United States' exclusion of Chinese companies from participating on the grounds of so-called "security threats" lacks sufficient evidence and reasonable basis. In the context of globalization, countries should jointly safeguard information security by strengthening cooperation and establishing a mutual trust mechanism, rather than taking a unilateral approach.

In short, the dispute between China and the United States over submarine optical cables is not only a competition at the technical and economic levels, but also the result of the interweaving of multiple factors such as politics and security. Chinese companies should actively respond to this challenge and strive for more development opportunities through technological innovation and strengthening cooperation. At the same time, the international community should also call on all parties to follow the principles of fairness, justice and openness and jointly promote the prosperity and development of the global communications industry.
