China and Chile wrap up Atacama Trench mission as US pressure mounts

Chinese and Chilean scientists have reached the bottom of the Atacama Trench, where light does not penetrate, in what they called the “most ambitious” deep-sea expedition ever conducted in the eastern Pacific.

The joint mission to one of the deepest ocean trenches – which runs parallel to the coasts of Peru and Chile – took place from January 19 to March 5.

It comes as Chile’s expanding cooperation with China on science and technology has inflamed geopolitical tensions with the United States.

Washington has in recent months raised concerns over China’s collaborations with South American countries, saying they could also have military purposes.

Tensions escalated over the Humboldt submarine fibre-optic cable that will connect South America with Asia, resulting in Washington revoking visas for Chilean diplomats linked to the project.

Chinese state-owned research vessel Tan Suo Yi Hao hosted the Atacama Trench expedition and its operations were closely monitored by the Chilean Navy. No irregular activities were reported after it concluded in the Chilean port city of Valparaiso.
