European Union foreign ministers are set to meet in Luxembourg on September 4 to address the migrant crisis, while the prime ministers of the Visegrad Group are to discuss the issue at an extraordinary summit in Prague.
The meetings come as a tense stand-off between police and at least 200 migrants on a train in Hungary continued into a second day.
On September 3, authorities let the migrants hoping to get to the Austrian border board a train in the capital, Budapest, but then tried to force them off at a refugee camp.
More than 350,000 people from conflict-hit states in the Middle East and Africa have crossed the Mediterranean in boats this year to reach Europe.
France and Germany say the EU should require member states to take in a minimum number of migrants, while the Visegrad Group, including the Czech Republic, Hungary, Poland, and Slovakia, opposes the idea of migrant quotas.
