AND then (!), the General Assembly is trying to pretend they are not wasting US Dollars on a pipe dream tax plan.

Summary
At a time where increased efforts to combat illicit financial flows and strengthen domestic resource mobilization have never been more urgent, the UN General Assembly has adopted a landmark Resolution on Strengthening International Tax Cooperation.

Description
With this, all UN Member States have committed to begin an intergovernmental tax process at the UN to evaluate options for further action, including an international tax cooperation "framework or instrument". The side-event will discuss these developments with a focus on the option of developing a new UN Convention on Tax, which has been proposed by a broad range of actors, including the Africa Group.
