UNITED NATIONS - Pakistan has warned the UN against establishing formal relationship with the Group of 20 industrialised countries as an observer, saying the world bodys position as an arbiter of international issues would be undermined. We are, in principle, opposed to decision-making in exclusive formats when those decisions have global significance and implications. We see this as undermining the cardinal principles of multilateralism, Ambassador Abdullah Hussain Haroon said Friday. Haroon made those forthright remarks in an intervention during the course of a briefing by UN Secretary-General Ban Ki-moon on the forthcoming G-20 summit in Canada. The UN chief is scheduled to attend the June 25-27 summit in Toronto at the invitation of G-20, which will discuss global economic and financial questions. The group comprises: India, Argentina, Australia, Brazil, Britain, Canada, China, France, Germany, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, U.S. and the European Union. After the briefing by the UN chief, the Pakistan ambassador said, We are not aware whether the invitation to participate in the G-20 Summit actually also indicates you will be involved in G-20 decision making. We have not heard any suggestions to that effect so far. Frankly, what we do not want to see, is for the UN Secretary-General or the United Nations and by implication, its membership to own or be associated with any decisions in whose finalization it has no voice or participation, he added. Referring to suggestions by some delegations to formalize a relationship between G-20 and UN, he posed a couple of questions: What is meant by formalization of relationship between a 'Charter body and an 'informal group. Will then happen to all such groups? Ambassador Haroon went on to say that for the UN to consider an observer status at the G-20, may not be commensurate with the world bodys status as the primus inter pares and is particularly unwarranted if the due weightage and respect of this institution is in any way compromised. He added, The suggestion of formally undertaking global economic governance and decision-making in Ad-Hoc groups and settings outside the UN, Pakistan has problems with this and asks is this not a new and disturbing future trend for the UN? Any global economic architecture must, in our view, ensure inclusiveness, transparency and full representation of all developing countries and promote full complementarities and coherence. This should remain the way forward at the UN.
