Indonesia has become more prominent in international organisations in recent years, serving as a non-permanent member of the UN Security Council in 2006-08 and taking a seat at meetings of the G20 group of the world's major economies. There is an opportunity for warmer relations with the US, given that the US president, Barack Obama, spent several years in Indonesia as a child. Ties with China are also likely to strengthen. Chinese businesses have become major foreign investors in a variety of sectors in Indonesia. Moreover, owing to the likelihood that the world's advanced economies will grow relatively slowly in the forecast period as they recover from the 2008-09 global recession, Indonesia will rely increasingly on China as an export market. However, there will be opposition to closer economic ties with China, as demonstrated by the backlash among local manufacturers against the free-trade agreement between that country and the Association of South-East Asian Nations (ASEAN) that took full effect in January 2010. Indonesia's foreign policy will continue to be influenced by the principle of non-alignment, and the government will resist becoming too closely associated with either the US or China. There will be intermittent disputes with Malaysia and Singapore over a range of long-standing issues. At the start of 2011 Indonesia took over the chair of ASEAN for one year.
