Nearly 200 countries spent a week locked in negotiations in Busan, South Korea , from November 25 with the goal of agreeing the first global treaty to curb plastic pollution.

The US government said Tuesday it was "disappointed" after nations negotiating a global treaty to curb plastic waste failed to reach a deal, blaming a "small group" of countries and producers for blocking progress. "A small group of countries and producers stood in the way of progress to protect their profits and perpetuate an inadequate status quo," it said.
