Ukrainian President Petro Poroshenko has said that the silence of the UN when a veto country in the organization violates its charter and principles is unacceptable.

"The UN shall not be silent when the values and principles rooted in its Charter and the entire body of international law are being violated by a veto country," Poroshenko said at the General Debate of the 73rd session of the UN General Assembly in New York on Wednesday.

He stressed that there was an opinion that the respect for peace was a constant given. However, appeasement and quick fixes to difficult problems have proven to be a false option, and now the aggressor continues its destructive policy, Poroshenko added.

According to the president, silence is exactly what the Kremlin weaponizes against Ukraine and, ultimately, against the whole international community.

Poroshenko added that in the absence of a strong and united reaction, "such extremely irresponsible and selfish actor resorts to the tactic of further escalation, creating new crises, raising the stakes, blackmailing other countries and even entire international organizations."
