More than 100 countries want the treaty to limit production as well as tackle cleanup and recycling, which is essential to address chemicals of concern.

Analysis: Deep divisions, obstructions by fossil fuel-producing countries and the missing voices of campaigners and experts all contributed to the collapse of talks, as Asia climate correspondent Stuti Mishra explains from Busan,

Negotiators at a U.N. plastic pollution summit in Busan, South Korea are pushing for a legally binding treaty that would set global plastic production reduction targets.

Negotiations on a treaty to end plastic pollution have concluded in Busan, South Korea without reaching an agreement.

Every year, the world produces more than 400 million tons of new plastic. Plastic production could climb about 70% by 2040 without policy changes.

By Joyce Lee and Valerie Volcovici BUSAN, South Korea (Reuters) -Negotiators on a treaty to curb plastic pollution face tough debate on the last day of scheduled talks, as over 100 countries support curbing production while a handful of oil-producing countries want to focus only on plastic waste.

Negotiators have failed to reach agreement on a landmark treaty to curb plastic pollution and need more time to continue discussions, the diplomat chairing the talks said Sunday.
