<P> When the countries' GDP is measured at purchasing power parity (PPP) rates, all 19 members are among the top 29 in the world for the year of 2014, according to the IMF . Iran (18), Taiwan (20), Nigeria (21), Thailand (22), Egypt (25), Pakistan (26), and Malaysia (28) are not G20 members, while Spain (16), Poland (23) and the Netherlands (27) are only included by virtue of being EU members . However, in a list of average GDP, calculated for the years since the group's creation (1999--2008) at both nominal and PPP rates, only Spain, the Netherlands, Nigeria, Poland, Taiwan, Iran and Thailand appear above any G20 member in both lists simultaneously . </P> <P> Spain, being the 14th largest economy in the world and 5th in the European Union in terms of nominal GDP, has been a "permanent guest" of the organization, and the Spanish government's policy is to not request official membership . A Spanish delegation has been invited to, and has attended, every G20 heads of state summit since the G20's inception . </P> <P> A 2011 report released by the Asian Development Bank (ADB) predicted that large Asian economies such as China and India would play a more important role in global economic governance in the future . The report claimed that the rise of emerging market economies heralded a new world order, in which the G20 would become the global economic steering committee . The ADB furthermore noted that Asian countries had led the global recovery following the late - 2000s recession . It predicted that the region would have a greater presence on the global stage, shaping the G20's agenda for balanced and sustainable growth through strengthening intraregional trade and stimulating domestic demand . </P> <P> Typically, several participants that are not permanent members of the G20 are extended invitations to participate in the summits . Each year, the Chair of the Association of Southeast Asian Nations; the Chair of the African Union; and a representative of the New Partnership for Africa's Development are invited in their capacities as leaders of their organisations and as heads of government of their home states . Additionally, the leaders of the Financial Stability Board, the International Labour Organization, the International Monetary Fund, the Organisation for Economic Co-operation and Development, the United Nations, the World Bank Group and the World Trade Organization are invited and participate in pre-summit planning within the policy purview of their respective organisation . Spain is a permanent non-member invitee . </P>
