The EU plans to make it harder for Russians to travel to the bloc by suspending a deal that eases their visa applications, while EU defence ministers consider a military training programme for Ukrainian forces.
European Union foreign ministers, meeting in Prague, may agree on tightening the issuance of visas for Russians and start debate on a wider ban on tourist visas though there is no agreement on that, EU officials have said.
An EU diplomatic source said on Monday that the foreign ministers may agree in principle on suspending a visa facilitation agreement with Russia, which would mean Russians would pay $80 instead of $35 for EU visas, and also face a more lengthy procedure.
"The result of Gymnich (foreign ministers' meeting) will probably not be an agreement to widen sanctions by including visas," the source told reporters.
"But (suspension of) the facilitation agreement will be the first step, and we will talk about how to include visas in the sanctions."
The Czechs, who hold the EU's rotating presidency, have themselves stopped issuing regular visas to Russians and have pushed for an EU-wide ban on visas for Russian tourists, an idea supported mainly by the Baltic countries.
The bloc's defence ministers, also meeting in Prague on Monday and Tuesday, will also discuss options for setting up an EU military training mission for Ukraine.
Several EU countries have been training Ukrainian troops for a while, mainly enabling them to operate weapons Western nations are delivering to Ukraine to help its fight against Russia's offensive.
It is not clear yet where an EU training programme could be based and what mandate it might have, EU diplomats told Reuters ahead of the defence ministers' meeting.
Some member states and the bloc's foreign policy and security chief, Josep Borrell, have opposed tightening Russian visas, arguing it might breach EU rules and cut off escape routes for Russian dissidents.
"I don't think that to cut the relationship with the Russian civilian population will help and I don't think that this idea will have the required unanimity," Borrell, who chairs EU foreign ministers' meetings, told the Austrian national broadcaster late on Sunday.
The EU source said there may be further discussions on how to slap sanctions on visas and that there may be exceptions for family members, civil society representatives or students.
Lithuanian Foreign Minister Gabrielius Landsbergis has said Estonia, Latvia, Lithuania, Poland and Finland, which all share a border with Russia, may act on their own to block tourists if the EU does not agree on a union-wide ban.
Russians mostly enter the EU via the land borders of the five countries since direct flights between Russia and the bloc were suspended following Moscow's offensive of Ukraine, according to Landsbergis.
In mid-August, Estonia closed its border to more than 50,000 Russians with previously issued visas, the first country in the EU to do so.
Ukrainian President Volodymyr Zelenskyy called on the West earlier this month to impose a blanket travel ban on Russians, drawing an angry rebuke from Moscow.
