The Russian government is proposing a new law to force foreigners entering the country to sign a loyalty agreement restricting what they can say about government policy and social values, the latest clampdown on freedom of expression by the Kremlin since its invasion of Ukraine.

The draft legislation set out by the Interior Ministry also states that foreigners must not discredit Russian authorities or officials, contradict Soviet military history or disrespect the country’s “spiritual and moral values,” according to TASS state news agency. If the law enters into force, foreigners would need to sign a consent form to enter the country. It couldn’t be determined what repercussions foreigners would face if they sign the proposed agreement and then violate it.
