Over the past four decades merchandise trade of developing Asian economies (DAEs) has grown at a much faster rate than growth in world trade, with a distinct intra-regional bias. Global production sharing has become a unique feature of the region's economic landscape, with China playing a pivotal complementary role as the premier assembly centre within regional production networks. According to the projections made using the standard gravity model of international trade, total real non-oil trade of DAEs would increase at an annual rate of 8.2 percent during the next three decades, with a notable convergence of individual countries' rates to the regional average. The share of intra-regional trade in total nonoil trade would increase steadily from 53 percent in 2010 to 58 percent in 2030. The trade-to-GDP ratio would increase from 39.4 percent and 74.4 percent between these two years.
