<h1>US-China Tensions Rise as Proposed Bill Seeks to Ban Student Visas for Chinese Nationals in Research Fields.</h1> China has criticized US efforts to restrict Chinese nationals from working in American research institutions, which has led to an exodus of researchers back to China. The US House 'Select Committee on the CCP' has raised concerns about national security risks, alleging that Chinese students exploit American universities for technological and military gains. A bill has been proposed to stop issuing student visas to Chinese nationals. In response, Chinese universities are attracting these researchers with lucrative positions. This trend has accelerated due to US policies, prompting many Chinese scientists to return home or move to other countries.
