We are finding that more and more countries are signing up for the port state measures agreement. Certainly, it would be beneficial if all countries did sign up for it, but the more countries that do sign up for it, the greater the opportunities it provides.
The PSMA is not the only mechanism. Just having port state measures, even without signing on to the agreement, are effective. Having agreements between countries that share a maritime boundary line and their being able to share information are important factors that feed into that. It's not necessarily just having to sign up to the PSMA. It's also having effective port state measures in place that address those issues.
