The WHO is creating a constitution and legally binding framework to dictate Global Health policy.
On 1 December 2021, the 194 members of the World Health Organization (WHO) reached consensus to kickstart the process to draft and negotiate a convention, agreement or other international instrument under the Constitution of the World Health Organization to strengthen pandemic prevention, preparedness and response.
In reality this is just formalizing the process wherein the WHO, a deeply corrupt and captured institution, supersedes local governments and dictates policy to all nations
This is what they mean by ''Global Governance'' it isn't conspiracy it's policy.
