Redirecting China Unicom fiber optic cable routes

China Unicom is expanding and redirecting its fiber optic network through major undersea and terrestrial projects, including the EMA undersea cable and the ERMC Eurasia terrestrial route.Undersea Cable ProjectsChina Unicom, along with other Chinese state-owned telecom companies, is a key participant in the EMA (Europe-Middle East-Asia) undersea cable network, a $500 million project led by HMN Technologies. The EMA cable will connect Hong Kong, Hainan, Singapore, Pakistan, Saudi Arabia, Egypt, and France, providing China-backed international connectivity independent of U.S.-influenced routes. This project is part of China's strategy to secure global data transmission channels and reduce reliance on U.S.-backed cables, potentially creating a divided global internet infrastructure with separate Chinese and American networks. The EMA cable is expected to be operational by 2025 . Chinese companies, including HMN Tech and FiberHome Marine Network Equipment, have become major players in submarine cable construction, with cumulative installations exceeding 100,000 km worldwide. These undersea cables are critical for global data traffic, carrying approximately 99% of international data and supporting digital economy growth, AI, cloud computing, and e-commerce in connected regions .Terrestrial Cable RoutesChina Unicom also operates terrestrial fiber optic routes, notably the ERMC (Europe-Russia-Mongolia-China) system, which connects Europe to China via Russia and Mongolia. The ERMC runs along the Mongolia Railway, with parallel optical cable routes of about 1,000 km each, linking southern and northern Mongolia through Sukhbaatar, Darkhan, Ulaanbaatar, Choir, and Zamyin Uud. This terrestrial network supports 100 Gbps DWDM transmission, offering a low-latency route from Hong Kong to Frankfurt (146 ms), and integrates OTN networks with ROADM nodes and reserve protection .Geopolitical and Strategic ConsiderationsThe redirection and expansion of China Unicom's fiber optic routes are influenced by geopolitical factors, including U.S. interventions that have previously blocked Chinese undersea cable projects over national security concerns. These interventions have led China to prioritize independent routes like EMA and ERMC to maintain global connectivity and protect data transmission from foreign control . By diversifying both undersea and terrestrial routes, China Unicom enhances resilience, reduces latency, and strengthens its strategic position in global telecommunications.ImplicationsGlobal connectivity: China Unicom's redirected routes improve access between Asia, Europe, and the Middle East, supporting international business and digital services.Data security: Independent Chinese routes reduce exposure to foreign surveillance and control.Economic impact: Enhanced fiber networks lower costs and enable digital infrastructure development in participating countries.Latency and redundancy: Terrestrial and undersea routes provide alternative paths, improving network reliability and speed. China Unicom's strategy demonstrates a coordinated effort to expand, redirect, and secure its fiber optic infrastructure across both undersea and terrestrial networks, balancing technical performance with geopolitical considerations .
