Brussels: European Union envoys are set to agree a new mechanism to punish chemical weapons’ attacks by targeting people blamed for using banned munitions regardless of their nationality, diplomats said.

The legal regime, based on a French proposal to combat what Paris and London say is the repeated use of chemical weapons by Russia and Syria, would allow the EU to impose sanctions more quickly on specific individuals anywhere in the world, freezing their assets in the bloc and banning them from entry.

Ambassadors from the EU’s 28 governments are expected to approve the regime at their weekly meeting on Wednesday, without debate.

The EU already has sanctions lists for Syria and Russia, but under the current system individuals must be added to special country lists. These are complex to negotiate and difficult to expand because some EU governments are reluctant to criticise close partners, particularly Moscow.

“This is significant because we will be able to add names without a big, sensitive debate,” said one senior EU diplomat involved in the negotiations. “We can try to uphold certain rights rather than just issuing statements.”
