The United States has pressed Argentina and Chile to review Chinese telescope projects located in the Andean desert regions, according to recent reports.

The telescope installations are part of China's expanding scientific presence in South America, where the high-altitude, clear skies of the Andes provide ideal conditions for astronomical observation.

The U.S. approach to the South American governments reflects broader strategic competition between Washington and Beijing across multiple sectors and regions. Both countries have been seeking to expand their influence in Latin America through various economic and technological partnerships.

Astronomers have expressed concerns that the review process could lead to setbacks in ongoing research projects. The scientific community relies on international collaboration and consistent access to observatory facilities for long-term studies.

Neither Argentina nor Chile has announced any immediate changes to the telescope projects. The facilities represent significant investments in the region's scientific infrastructure and contribute to both countries' research capabilities.
