Who is supporting the WHO's pandemic treaty?

UPDATE: India has joined the list of countries that support giving the WHO more powers.

At the second Global COVID Summit, Prime Minister Narendra Modi said, "It is clear that a coordinated global response is required to combat future health emergencies. We must build a resilient global supply chain and enable equitable access to vaccines and medicines… We also call for streamlining WHO's approval process for vaccines and therapeutics to keep supply chains stable and predictable. As a responsible member of the global community, India is ready to play a key role in these efforts."
