GENEVA (AP) — After the coronavirus pandemic triggered once-unthinkable lockdowns, upended economies and killed millions, leaders at the World Health Organization and worldwide vowed to do better in the future. Years later, countries are still struggling to come up with an agreed-upon plan for how the world might respond to the next global outbreak.

A ninth and final round of talks involving governments, advocacy groups and others to finalize a “pandemic treaty” is scheduled to end Friday. The accord’s aim: guidelines for how the WHO’s 194 member countries might stop future pandemics and better share scarce resources. But experts warn there are virtually no consequences for countries that don’t comply.

WHO’s countries asked the U.N. health agency to oversee talks for a pandemic agreement in 2021. Envoys have been working long hours in recent weeks to prepare a draft ahead of a self-imposed deadline later this month: ratification of the accord at WHO’s annual meeting. But deep divisions could derail it.
