The 193-nation U.N. General Assembly on Tuesday overwhelmingly approved the first treaty on the global arms trade, which seeks to regulate the $70 billion business in conventional arms and keep weapons out of the hands of human rights abusers.

The official U.N. tally showed 154 votes in favor, 3 against and 23 abstentions, though diplomats and U.N. officials said the actual vote was 155-3-22 due to Angola being recorded as having abstained and not voting yes. Venezuela, which said it had planned to abstain, Zimbabwe and three other countries were not allowed to vote because they were in arrears on their U.N. dues.
