A unified Thai kingdom was established in the mid-14th century. In alliance with Japan during World War II, Thailand became a US ally following the conflict. Thailand then went through a series of coups d'état, but eventually progressed towards democracy in the 1980s. With a well-developed infrastructure, a free-enterprise economy, and pro-investment policies, Thailand appears to have fully recovered from the 1997-98 Asian Financial Crisis. The country was one of East Asia's best performers from 2002-04. Boosted by increased consumption and strong export growth, the Thai economy grew 6.9% in 2003 and 6.1% in 2004 despite a sluggish global economy. Bangkok has pursued preferential trade agreements with a variety of partners in an effort to boost exports and to maintain high growth. In December, the Thai Board of Investment reported the value of investment applications from January to November had declined by 27% year-on-year. On the positive side, exports have performed at record levels, rising nearly 17% in 2006. Export-oriented manufacturing, in particular automobile production, and farm output are driving these gains.
