UNITED NATIONS, Oct 12 (Reuters) - The United Nations General Assembly on Wednesday overwhelmingly condemned Russia's "attempted illegal annexation" of four partially occupied regions in Ukraine and called on all countries not to recognize the move, strengthening a diplomatic international isolation of Moscow since it invaded its neighbor.Three-quarters of the 193-member General Assembly - 143 countries - voted in favor of a resolution that also reaffirmed the sovereignty, independence, unity and territorial integrity of Ukraine within its internationally recognized borders.Ambassador Vassily Nebenzia told the General Assembly ahead of the vote that the resolution was "politicized and openly provocative," adding that it "could destroy any and all efforts in favor of a diplomatic solution to the crisis."U.S. Secretary of State Antony Blinken convened a virtual meeting on Tuesday with diplomats from more than 100 countries.As Russia and the West have vied for diplomatic influence, some states - particularly in the global South - have grown concerned about paying the price for being squeezed in the middle of an intense geopolitical rivalry."
