Prime Minister John Key says a draft Security Council resolution on Syria does not go far enough in ensuring the Syrian regime is held to account for the use of chemical weapons.
At about midday (NZ Time), the Security Council's 15 members will meet to vote on the draft resolution hammered out by Russia and the US, as well as the other permanent members, the UK, China and France.
It requires Syria to hand over its chemical weapons, and allows the Security Council to take further action if Syria does not comply, but does not specify what actions the Council can take to ensure that happens, or how the regime will be held to account.
Those issues will have to go back before the Security Council at a later date, and run the risk of a Russian veto of any serious action such as the use of force.
Mr Key said he did not believe the resolution went far enough in holding the Assad regime to account for it.
