The Vietnam Posts and Telecommunications Group (VNPT) has announced that it is joining in the development of the new Southeast Asia Japan 2 underseas cable (SJC2) project. The SJC2 will cost $439 million USD and have a bandwidth of 126 Tbps (Terabytes Per Second), the largest bandwidth of any underseas telecommunications cable serving Vietnam.

SJC2 will serve mainland China, Japan, Singapore, South Korea, Taiwan, Thailand and Vietnam and will include the participation of the regions major telecom companies, including China Mobile International, Indonesia’s Telin Telecom, Singapore’s Singtel, South Korea’s SK Broadband and Taiwan’s Chunghwa Telecom.

In Vietnam, the SJC2 point of connection is planned to be Quy Nhon Town in Binh Dinh province which is located in the south of the country. SJC2 will be the sixth marine cable to serve Vietnam that VNPT has invested in.

Vietnam, which has a pollution of 93 million people, and regularly sees more than 65% of the population online, is currently connected to six undersea cables and a 120-gigabit overland cable from China.

The country’s main broadband connection has been through the Asia Pacific Gateway (APG) undersea cable, which has a bandwidth of 54 Tbps. Since coming online in 2016, the APG connections with Vietnam have been broken an average of 3 times each year, causing problems for both businesses and consumers trying to access the internet.

Another Vietnamese telecom company, military-run Viettel announced earlier in the year that will join with China Telecom, India’s Tata Communications, Japan’s SoftBank, and Singapore’s Singtel to install a 9,400-km submarine cable that would serve Vietnam through a new 140 Tbps cable that is expected to operational at the end of 2022.
