Syria’s foreign minister said on Tuesday night that the country intends to sign up to the Chemical Weapons Convention (CWC) and would halt its production of chemical arms, allow weapons inspectors in and disclose details of its chemical weapon stockpile.
The Chemical Weapons Convention was adopted by member states in 1992 and came into force in 1997. Signatories pledge not to use chemical weapons, to halt any trade or production of chemical weapons and to destroy their stockpile within ten years of signing. Syria is not the only state that has refused to sign the convention. Four other states, Angola, Egypt, North Korea and South Sudan have not signed up, and Israel and Myanmar signed the convention but never ratified it.
As South Sudan only achieved independence in 2011, perhaps it can be let off the hook – the world’s newest state, it could be argued, has had bigger problems to deal with. It’s hardly surprising that North Korea hasn’t signed, although this doesn’t make it less worrying. Egypt has said its refusal to sign the CWC is linked to Israel’s non-participation in the treaty on the non-proliferation of nuclear weapons. It used chemical weapons in Yemen in the 1960s. Angola has no officially confirmed stockpile of chemical weapons, although there are several reported incidents  of chemical weapons having been used in the country.
Similarly, Israel’s delay in ratifying the CWC has raised questions about its possession of chemical weapons – with this recent Foreign Policy investigation  suggesting, on the basis of CIA files, that it has built up a significant stockpile. Questions still loom about Myanmar’s chemical weapon stockpile too, and its alleged use of chemical weapons  during the country’s civil war.
Even more revealing is the list of those who have signed up but who will not meet the Convention’s deadlines for destroying their chemical weapons stockpile. This includes the United States and Russia, a recent enthusiast for the treaty when it comes to Syria.
So how much power will the CWC actually have? Both Russia and the US must know that unless it is backed by force, the answer is none at all. Equally they will be aware that sometimes the easiest way to deal with awkward international treaties is to sign them to much fanfare and then quietly ignore them.
