The European Union threatened to impose new sanctions on Belarus as the border crisis deepens.
Thousands of people remain stranded in freezing conditions on both sides of the Belarus-Poland border, barred from entering the EU.
The EU foreign ministers are expected to approve the new sanctions on Monday.
The sanctions may also target airlines and travel agents who transported asylum seekers to Belarus.
The move came as the Belarus-Poland border crisis escalates, with thousands of migrants and refugees stranded near the frontier, hoping to enter the EU.
Meanwhile, hundreds of people are now living in a tent camp on the Belarus-Poland border in near-freezing temperatures. Poland, which has established a state of emergency in the border region enforced by hundreds of troops, refuses to allow them in.
However, the incident has led to international condemnation from the EU, US and NATO and renewed threats of sanctions.
Poland and other EU states accuse Belarus of encouraging the migrants and refugees to cross in revenge for Western sanctions on Minsk over President Alexander Lukashenko’s crackdown on dissent after last year’s disputed election.
Poland has earlier deployed 3,000 more soldiers to strengthen the border as tension mount between the two countries
More than 2,000 asylum seekers and refugees remained on Poland-Belarus borders for several weeks. This came after Polish authorities refused to let them in.
Their numbers have unprecedentedly risen over the past few weeks amid tension between Belarus and Poland.
