Military officials from more than 30 nations will take part in Paris talks on the creation of an international security force for Ukraine, a French military official said Monday.

Such an international force would aim to dissuade Russia from launching another offensive after any ceasefire in Ukraine comes into effect.

The force being envisaged by France and Britain would aim to reassure Ukraine and deter another large-scale Russian offensive after any ceasefire, the official said. It could include heavy weaponry and weapons stockpiles that could be rushed within hours or days to aid in Ukraine’s defense in the event of a Russian attack that shatters any truce, the official said.

Chiefs of staff — or, in Canada’s case, their representative — from nearly all of the 32 nations of the NATO military alliance will attend the Paris discussions. Three NATO nations will be absent. They are Croatia and Montenegro, which were invited but didn’t respond, and the United States, the official said.
