UNITED NATIONS - Ban Ki-moon, who was unanimously approved by the UN General Assembly on Tuesday for a second five-year term as the secretary-general, said he would work as a "harmonizer and bridge-builder among member states," to advance the cause of world peace in these turbulent times. Ban, who is seen as a solid US ally, told the 192-member Assembly that he was proud and humbled to accept the appointment. As Secretary-General, I will work as a harmonizer and bridge-builder among Member States, within the UN system, and between the UN and a rich diversity of international partners, Ban said. He stressed that no challenge is too large. Together, nothing is impossible, he said, noting that the worlds peoples are looking more and more to the UN to lead on key issues. We knew then and more so now that we live in an era of integration and inter-connection, a new era when no country can solve all challenges on its own and where every country should be part of the solution. That is the reality of the modern world.
