Intra-GCC trade has also grown rapidly at 32.4 percent over the same period, although it represents a minority share of its total trade. The significance of intra GCC trade varies between member states. Intra-GCC trade has the highest significance for Oman, representing 30 percent of all imports and 51 percent of all non-oil exports. Oman is also a significant source of certain key commodities to its GCC partner countries and also a significant market for exporters in other GCC countries. Trade relations between the sultanate and the GCC states since their start are marked by steady growth in the economic and commercial fields, having exceeded RO.659 million at the end of 2007. This growth received a big boost after the last Gulf summit conference in Qatar approved the establishment of a GCC common market and unified customs' tariff. Intra GCC trade represented 5.1 percent of the region's total trade with the world in 2007. It represented 8.2 percent of total imports and 7.8 percent of total exports in 2007. If oil is excluded, intra GCC trade's share is slightly higher at 9 percent of total trade, 15 percent of imports and 26 percent of exports in 2007. The major intra Gulf exporters in 2007 was Saudi Arabia with an estimated 44 percent of all exports to the GCC by a GCC country, followed by the UAE with an estimated 38 percent of all exports to the GCC. Together these two countries, make up 82 percent of all exports to the GCC by member countries. The remaining 17 percent of intra-GCC exports in 2007 came from Oman (7 percent), Qatar (4 per cent), Kuwait (4 percent) and Bahrain (3 percent). From a low base of RO.143 million in 2001, Oman's non-oil exports to the GCC grew to RO.659 million in 2007 with 55.5 per cent year on year growth. In 2001, whilst non-oil exports to the GCC were RO.143 million, re-exports were RO 280 million. In 2007, non-oil exports and re-exports to the GCC countries were RO.659 million and RO.699 million respectively. The non-oil exports in 2007 included 309 products with a minimum value of RO.10,000. The bulk (74 percent) of the non-oil export value came from 20 products. Growth in imports from other GCC countries to Oman peaked in 2004 with a 64.9 percent increase. In 2006 and 2007, they grew 19.8 percent and 44.2 percent respectively. This means that the value of imports from the GCC countries has more than doubled from RO.740 million in 2001 to RO.1,854 million in 2007. As much as 79 percent of the sultanate's non-oil exports to the GCC countries went to the UAE in 2007. Saudi Arabia was the next largest export market in the GCC with 9 percent of non-oil exports to the GCC going there. The RO.1,854 million imports from the GCC countries in 2007 covered 3,137 products of a minimum value of RO.10,000. Of these, 62 commodities with a value in 2007 of RO 5 million or more constituted 48 percent of the total imports from the GCC. Intra-GCC trade represents 30 percent of total imports and 51 percent of non
