West piles sanctions on Belarus after plane diversion
"We are united in our deep concern regarding the Lukashenko regime’s continuing attacks on human rights, fundamental freedoms, and international law," they said in a joint statement.
US Secretary of State Antony Blinken said the measures "demonstrated the steadfast transatlantic commitment to supporting the Belarusian people's democratic aspirations".
The EU and the US both targeted dozens of individuals and entities over a brutal crackdown on opposition since Lukashenko claimed victory in elections last August deemed fraudulent by the West.
EU foreign ministers meeting in Luxembourg also backed broad-ranging sanctions targeting major revenue sources for the Belarusian regime: potash fertiliser exports, the tobacco industry, petroleum and petrochemical products.
"Today we have confirmed and decided that sectoral sanctions will be taken against Belarus, which will have a severe impact on the Belarusian economy," German Foreign Minister Heiko Maas said ahead of the meeting.
"We want the release of the political prisoners, an end to the violence against protesters and the opposition, and an inclusive dialogue that will lead to free and fair elections."
Belarusian opposition leader Svetlana Tikhanovskaya, who insists she rightfully won last year's poll, welcomed the EU's inclusion of business tycoons and top officials on the blacklist.
"It's a rather strong sanction list," she told a press conference in Brussels.
Belarusian strongman Lukashenko sparked international outrage by dispatching a fighter jet on May 23 to intercept the Ryanair plane flying from Greece to Lithuania.
The EU responded quickly by blocking Belarusian airlines from flying to the bloc and stopped carriers from its 27 nations from using Belarusian airspace.
The bloc had already slapped sanctions last year on 88 individuals -- including Lukashenko and his son -- over a brutal crackdown on protests since the veteran leader claimed victory at elections in August deemed fraudulent by the West.
The US imposed a slew of sanctions on Belarusian state-owned companies in May after authorities forced the Ryanair flight to land in Minsk by alleging a bomb threat.
The Belarusian authorities detained thousands during the demonstrations sparked by last year's election and the EU says that some 500 political prisoners remain behind bars.
"We are clearly showing that Stalinism and state terror no longer have a place in the 21st century," Luxembourg Foreign Minister Jean Asselborn said.
Lukashenko, ruler of Belarus since 1994, has so far shrugged off the pressure with backing from his key ally Russia.
Lithuania's Foreign Minister Gabrielius Landsbergis complained that Belarus was hitting back by sending migrants, mostly Iraqis and Syrians, across its border.
He warned the flow could increase after sanctions were approved and that Lithuania "might need help and assistance from other European countries".
