UN General Assembly president Volkan Bozkir on Monday criticized the Security Council, saying it was failing to respond to world's biggest challenges due to "competing interests."

"The council has, on many occasions, failed to carry out its responsibility to maintain international peace and security," Bozkir, a Turkish diplomat, said at a debate on reforming the body.

"Competing interests among its members and frequent use of the veto have limited the Security Council's effectiveness. Even in some of the most urgent humanitarian crises, the council could not provide a timely and adequate response."

There has been growing criticism of the body, which has not been reformed in decades, with France's President Emmanuel Macron saying in a recent interview with Le Grand Continent that it "no longer produces useful solutions."

Bozkir said reform of the Security Council was "an unavoidable imperative -- both challenging and essential."

Since the outbreak of the Covid-19 pandemic, the Security Council has held few meetings devoted to the virus.

It took more than three months to overcome the friction between the United States and China to pass a resolution on July 1 calling for more international cooperation and to support a call by the secretary-general for a ceasefire in war-torn countries to help fight the disease.

During the debate on reform, the 193 UN members will discuss the right to veto, the privilege of the five permanent members of the Security Council (United States, China, Russia, France and the United Kingdom), enlarging the forum and its regional balance.

The Security Council, which can decide on international sanctions and the use of force, has 15 members. In addition to the five permanent nations, it has 10 non-permanent members elected for two-year terms.
