Istanbul, Oct. 11 (DHA) - Escalating trade tensions between the U.S. and China could undo global progress in helping end extreme poverty, World Bank (WB) President Jim Yong Kim said Thursday at the outset of bank’s annual meeting with the International Monetary Fund (IMF) and other financial institutions.Threats to growth and the trade that helps drive it are overshadowing the gathering of finance officials, central bankers and other leaders on the Indonesian island of Bali, a tropical tourist destination that reflects Indonesia’s own rapid development over the past three decades.Kim joined IMF chief Christine Lagarde and others in warning of the risks to world growth and economic development from threats to world trade after the U.S. imposed tariffs on tens of millions of dollars of Chinese exports and Beijing responded with similar retaliatory taxes on imports of U.S. goods.\"We’re very concerned about trade tensions\" Kim said. “Trade is very critical because that is what has lifted people out of extreme poverty. I am a globalist. That is my job. That is our only chance of ending extreme poverty. We need more trade not less trade\" he added.
