BEIJING: Chinese President Xi Jinping called on countries to protect the “central role” of the United Nations in international affairs, urging his Brazilian counterpart on Friday to help safeguard international norms, state media reported. The comments come after US President Donald Trump unveiled plans for his new “Board of Peace” at the World Economic Forum. Although originally meant to oversee Gaza’s rebuilding, the board’s charter does not seem to limit its role to the Palestinian territory and has sparked concerns Trump wants to rival the United Nations.
