What I can say is I believe it's true that there have been 11 countries that have acceded to the treaty to date. In addition to that, if memory serves, there are, I think, a total of 35 or so that have signed the treaty or otherwise the state in question has indicated its intent to ratify the treaty. There are dozens of countries, more than enough to bring this treaty into force, that, like ourselves, have signalled an intent to ratify and are moving through to take the necessary domestic measures to do so.
Obviously, regulatory and legislative systems vary widely across the world when one is speaking of a global treaty, but we believe this treaty does enjoy a significant international global consensus around it.
