(Bloomberg) -- The Biden administration announced it would re-impose sanctions against nine Belarusian state-owned enterprises and is developing additional penalties to target officials in the administration of President Alexander Lukashenko over the forced landing of a Ryanair Holdings Plc jetliner and the arrest of a dissident journalist.

The administration has also issued a “Do Not Travel” warning to American citizens urging them to steer clear of Belarus and issued a notice to American pilots to “exercise extreme caution” when considering flying in Belarusian airspace, White House press secretary Jen Psaki said in a statement on Friday night.

The Treasury Department is also crafting an executive order that will “provide the United States increased authorities to impose sanctions on elements of the Lukashenko regime, its support network, and those that support corruption, the abuse of human rights, and attacks on democracy,” Psaki said.

“Belarus’s forced diversion of a commercial Ryanair flight under false pretenses, traveling between two member states of the European Union, and the subsequent removal and arrest of Raman Pratasevich, a Belarusian journalist, are a direct affront to international norms,” Psaki said in the statement.

Belarus earlier this week forced the landing of a jetliner carrying Raman Pratasevich, a Belarusian journalist and outspoken critic of the Lukashenko regime, as it was traveling between Greece and Lithuania. Pratasevich, 26, has been detained in Minsk alongside his girlfriend, Sofia Sapega, despite international calls for their release.

European Union officials on Thursday detailed plans for their own sanctions against Belarus that would hit economic sectors close to Lukashenka, including the country’s potash industry. Those are likely to have a greater impact than the penalties announced by the White House; U.S. trade with Belarus amounted to only about $112 million in 2020, according to the U.S. Census Bureau.

The announcement came after some lawmakers earlier this week called for the Federal Aviation Administration to fully prohibit U.S. aircraft from entering Belarus air space after the episode. The U.S. is suspending its discretionary application of the 2019 U.S-Belarus Air Services Agreement, the White House said.

Russia has backed Lukashenko over the past quarter century, including during a brutal crackdown on the opposition last year, even as he resisted Moscow’s push for closer economic and political union. Even so, he has been adept in the past at playing off the EU and Russia against each other to retain his independence.

Russian President Vladimir Putin warmly greeted Lukashenko in the Black Sea resort of Sochi on Friday.

“I’m very happy to see you,” Putin said, agreeing as Lukashenko belittled Western criticism of the airliner incident as “a surge of emotions.”
