The European Union is set to agree new sanctions against Russia, targeting its finance, energy and defence sectors over the conflict in Ukraine.
Top Russian individuals and entities are already subject to EU sanctions for their alleged role in Ukraine’s crisis.
Calls for the EU to act have been fuelled by the downing of flight MH17.
An international team has again failed to access the crash site in eastern Ukraine, amid heavy fighting between government forces and rebels there.
This is the third time in as many days that the team, which includes Dutch and Australian police officers, has had to abandon attempts to reach the site. Many of the 298 people travelling aboard Malaysia Airlines flight MH17 were Dutch or Australian.
Earlier on Tuesday, Dutch Prime Minister Mark Rutte asked Ukrainian President Petro Poroshenko to “halt hostilities” around the crash site, according to a spokesman for Mr Rutte, quoted by AFP news agency.
