In the contest between the US and China for dominance over the world’s technology infrastructure, the latest battle is taking place under the Pacific Ocean.

While the US has been upping the pressure on its allies not to include equipment made by Chinese telecom giants like Huawei and ZTE in their 5G systems, Chinese companies have gained a foothold in some of the world’s most essential communications infrastructure – undersea internet cables.
Almost all global data communications flow through cables under the ocean – just one per cent travels by satellite – and Chinese companies have quietly been eroding US, European and Japanese dominance over the backbone of the internet, the undersea cable market. Now, they have trained their sights on connecting one of the most virtually remote parts of the globe, the Pacific Island countries.
Of the 378 cables currently operating worldwide, 23 are under the Pacific. But many of these cables run right by Pacific Island nations on their paths between hubs in Los Angeles, Tokyo and Singapore.

Despite the volume of data flowing under the Pacific Ocean, just half a million of the 11 million people living in Pacific Island countries and Papua New Guinea – less than five per cent – have access to a wired internet connection and only 1.5 million to a mobile connection, according to the United Nations Economic and Social Commission for the Asia Pacific (UNESCAP), compared with 53 per cent of people in Thailand and 60 per cent in the Philippines.
More than US$4 billion worth of cables are to come into service by 2021, continuing a trend in which US$2 billion worth of cables have come online every year since 2016, and six of these cables will connect Pacific Island countries.
