It also plans to build eight internet data centers in countries involved in the Belt and Road Initiative within three years, and build new submarine cables and international communication services' gateways to Asia, Europe and the United States.

A 25,000-kilometer submarine cable system linking Asia, Africa and Europe has entered service, as China United Network Communications Group, a key participant in the cable project, accelerates steps to build internet infrastructure for countries and regions related to the Belt and Road Initiative.

The AAE-1 is the world's largest submarine cable system built in more than a decade.

China Unicom said with AAE-1, it will become the only operator in China to have two submarine cable systems to connect Asia, Africa and Europe.

The move is part of the company's broad efforts to build international submarine cable infrastructure.

The State-owned company said it has built more than 30 submarine cables.

The submarine cable project is designed to possess the largest data transmission capacity between Africa and South America, as well as provide high-quality and reliable intercontinental telecom services.

Fu Liang, an independent telecom expert, said most international data are transmitted by wires at the bottom of the ocean called submarine communications cables.

The Royal Thai Navy (RTN) on May 8 signed a contract with a Chinese company to procure a S26T diesel-electric submarine.

cn]The Royal Thai Navy (RTN) onxa0Monday signed a contract with a Chinese company to procure a S26T diesel-electric submarine, a move experts believe will promote China's export of conventional submarines.

According to CSIC's official website, this is the company's second submarine export contract, after an eight-ship deal with Pakistan's navy in 2015.

The S26T will be the RTN's first submarine since the end of World War II.

Due to domestic politics and a budget shortage, the country delayed its plan to buy a submarine until China offered an unbeatable deal.

China's independently developed "Haijing" system, a marine seismic exploration and acquisition equipment using submarine cables, completed its first 3,000m-deep seabed geology exploration on Thursday, 500 kilometers south of Zhuhai in South China's Guangdong province, said its operator China National Offshore Oil Corporation (CNOOC).

Seismic exploration is the most direct way to find oil and gas resources in the vast depths of the ocean, and submarine cable-enabled seismic exploration technology is the most direct, cost-effective and efficient method for seabed geological structure detection.

Such infrastructure will include optical cables, cross-border interconnectivity facilities, international submarine cables, next-generation mobile communication networks and data centers, said the NDRC.

The construction of a series of submarine communication cables and computing infrastructure in Shantou, a coastal city in Guangdong province, will help provide low-cost and efficient linkage support for two-way data transmission for domestic and foreign companies, according to a senior local Party official.

Wen said construction of an Asian direct high-speed submarine cable and a second Southeast Asia-Japan submarine cable will be completed in Shantou by the end of 2023 and next year, respectively.

Following completion of the two submarine cables, the outbound bandwidth from Shantou will account for nearly half of the country's total.

"Shantou's sea area is very suitable for laying new international submarine cables, with the advantage of global direct coverage being further highlighted in the future.

"Shantou, one of the three major submarine cable landing stations on the Chinese mainland, currently has four international submarine cables directly connected to more than 30 countries and regions in the Asia-Pacific, Southeast Asia, Europe, the Americas and Oceania.

Shantou is one of the three Chinese cities with a landing station for international submarine cable, an advantage for more efficient data transmission.

The underwater data center will employ information technology facilities such as servers in seabed cabins, using submarine composite cables to power transmission of data back to onshore internet data stations.

As of December, it had built three international communication submarine cables, 12 international terrestrial optical cables and 13 key communications nodes, according to the Guangxi big data development bureau.

"The initiative will play an important role in enhancing Thailand's digital infrastructure as the central hub of the region by connecting neighboring countries through the submarine cable, which is a crucial step toward the success of high-speed internet access and connectivity in regional, subregional and remote areas," he added.

Yao Siyang, the chief executive officer of China Unicom Global, Africa, said the company has rallied behind the continent's digitization efforts through investment in supportive infrastructure like submarine cable.

"We have one dedicated submarine cable from Cameroon to Brazil and for the telecom companies, we also do connectivity and voice," Yao told Xinhua during an interview Tuesday.

He said that by participating in Africa Telecoms Week, China Unicom looked forward to establishing new partnerships with mobile operators besides introducing its new products including security for cloud and new submarine cable solutions.

Production capacity of equipment such as submarine communication cables is steadily improving.

The first LNG receiving terminal funded by a domestic private enterprise will start construction of its submarine pipelines this year in Zhejiang province, and upon completion, it will reach an annual handling capacity of 3 million metric tons in 2020, said CEO of ENN Group.

Work on laying several international submarine cables has made substantial progress, with 130 cross-border terrestrial cable systems already built.

The SEA-H2X submarine cable project is a case in point.

Aye Aye Myint, an employee of China Unicom's local unit in Myanmar, has been involved in a submarine cable project that connects China and Myanmar.

"This long submarine cable not only brings information and communication services to various destinations, but also strengthens ties between China and overseas Chinese like me," she said.

Investing in advanced digital information infrastructureAs consortium investors for extensive numbers of international submarine and terrestrial cable systems, the robust and accessible global telecommunications network of China Unicom guarantees global users with the state-of-the-art experience in converged computing-networking, and integrated cloud-network-edge services.
