U.S. government-backed broadcaster Radio Free Asia reports Switzerland has halted virtually all science and technology cooperation with North Korea except for medical research.

The report says the Swiss government Wednesday revised its enforcement of UN Security Council sanctions to suspend most science exchanges.

It means North Korean students are banned for now from studying electric or mechanical engineering and similar subjects at higher educational institutions in Switzerland. 

The measure is in compliance with UN Security Council Resolution 2321, in which member states are prohibited from pursuing cooperative projects that could help North Korea enhance its weapons of mass destruction capabilities.
