China–Brazil Launch Joint Space Tech Lab Amid US Concerns

China–Brazil Boost Space Cooperation with New Joint Astronomy Laboratory

China and Brazil have taken a major leap in their long-standing space collaboration by establishing a Joint Laboratory for Radio Astronomy Technology , reinforcing bilateral scientific ties at a time of rising global competition in high-tech sectors. The lab is being set up through cooperation between CETC’s Network Communications Research Institute and two leading Brazilian federal universities, signalling both nations’ intention to expand frontier research in astronomy and deep-space exploration.

A New Hub for Advanced Space Research

The upcoming laboratory will focus on cutting-edge work in observational astronomy, development of precision instruments and deep-space technology. It aims to serve as a central platform for innovation, enabling researchers from both countries to co-develop tools and methodologies essential for next-generation space studies.

Geopolitical Backdrop and Regional Shifts

The initiative comes at a time when the United States is urging Latin American countries to limit strategic partnerships with China, particularly in space and monitoring technologies. Washington argues that Chinese-operated systems could enhance Beijing’s surveillance reach, a claim China dismisses as politically motivated. Despite these tensions, Brazil has chosen to maintain and deepen its scientific engagement with China.

Progress on the BINGO Radio Telescope

A prominent example of ongoing cooperation is the BINGO radio telescope , designed to map cosmic structures and investigate dark energy. Its primary structure, built in China, has already arrived in Brazil, with completion expected in 2026 . Once operational, BINGO will be South America’s largest radio telescope , contributing to cosmic studies as well as tracking satellites, meteoroids and near-Earth objects.

Exam Point

• Joint Lab: Collaboration between CETC and two Brazilian federal universities .

• BINGO will be South America’s biggest radio telescope (to be completed in 2026).

• US pressure has led to the freezing of Chinese telescope projects in Chile and Argentina .

• China uses space cooperation as a diplomatic instrument across Asia, Africa and South America.
