Thailand had one of the world’s fastest growing economies from the 1960s to the late ’90s. By the 1990s Thailand was considered to be part of a second wave of newly industrializing countries, or NICs, that included such countries in the region as Malaysia and Indonesia and that were following fast on the heels of such first-wave NICs as South Korea and Singapore. Unlike Japan and some of the first-wave NICs, where governments aggressively channeled capital into industrial sectors with high growth potential, Thailand relied on an independent central bank and other government financial agencies to create the proper conditions for economic growth and left it to the private sector to make specific business decisions. This growth substantially improved the standard of living in Thailand, especially among urban dwellers. In July 1997, however, a crisis in Thailand’s financial markets forced the government to institute a drastic devaluation of the Thai currency, the baht, which triggered a wider crisis that soon swept across most of East and Southeast Asia. The crisis was especially severe in Thailand, where many financial institutions collapsed or were taken over; without new sources of capital, construction and new economic ventures slowed to a near halt. These events compelled the Thai government, with the backing of the International Monetary Fund, to institute a series of economic reforms, especially in the financial sector, after which the economy slowly began to recover.

Several factors led to Thailand’s financial collapse. Among these were the wholesale financial liberalization of the early 1990s; the declining competitiveness of Thailand relative to China, Vietnam, and other Asian countries; the aggressiveness of Thai businesses in obtaining short-term loans from foreign sources to fund long-term obligations; the eagerness of international lenders to make these loans; the growing influence from the mid-1990s of political leaders over the previously independent Bank of Thailand and other governmental economic agencies; the lax regulation of financial markets and the Securities Exchange of Thailand by the Bank of Thailand and other government bodies; and the slowness of the authorities to act once the problems were recognized. Foremost among those responsible for the crisis were the many finance companies that made short-term loans to fund long-term property investments. These finance companies were the first financial institutions to collapse. In the aftermath of the crisis, major banks and financial institutions went bankrupt, were combined with other firms, or were purchased by foreign buyers.

Even before the onset of the economic crisis, there was already ample evidence that the country’s rapid economic growth—while having brought a definite rise in the standard of living of most Thai—was also creating many social problems. Notable among the undesirable consequences were increased environmental pollution and degradation, a widening gap between rich and poor, the growth of slums and overcrowding in the cities, and urban traffic congestion. Added to these problems was the emergence of an HIV/AIDS epidemic in Thailand, which became the most serious in Asia. Increasingly, many of the NGOs and business leaders, even the king himself, have questioned the single-minded pursuit of new investments in industry and services, proposing instead that the country seek sustainable development that respects traditional ideas of community.

In contrast to the ideal of sustainable development, the government of Thaksin Shinawatra strongly emphasized free-market economics, and its policies succeeded in stimulating significant new growth in the economy. The Thaksin government used increasing revenues to undertake a number of large-scale infrastructure projects, the most visible of which was the Suvarnabhumi international airport. However, these projects also brought accusations of corruption and shoddy workmanship—notably the discovery of structural flaws at the new airport shortly after it opened—and questions were raised about how beneficial such projects were to the country’s economy.

From the 1950s through the ’70s, Thailand’s foreign policy was based on anticommunism and a special relationship with the United States. The withdrawal of American forces from Vietnam and the establishment of communist regimes in Vietnam, Cambodia, and Laos spurred Thailand to reassess its foreign policy, and since the 1980s the emphasis has been more on promoting economic relations than on security. The relationship with the United States has been downgraded, and closer ties have been forged with Japan and China. Following the end of the Cold War and the disintegration of the Soviet Union, Thailand began to encourage regional trade relationships, even with its former enemies—Vietnam, Laos, and Cambodia.

Thailand was a charter member of the Association of Southeast Asian Nations (ASEAN), and with its support Vietnam, Laos, Cambodia, and Myanmar were all admitted to the organization between 1995 and 1998. Although ASEAN had not evolved into a free-trade bloc, by the early 21st century Thailand had become increasingly oriented toward other Asian countries with which its economic relations had been strengthening, most notably China.

Although economic concerns have been the underlying basis for Thailand’s foreign policy since the 1980s, security concerns have not disappeared. The country has continued to grapple with refugees on its western border with Myanmar. At the same time, conflicts in southern Thailand have contributed to the government’s willingness to work with the United States and others in efforts to control terrorists who have been identified as Islamic radicals.

In 2008 Thailand became embroiled in a military confrontation with Cambodia over the status of the Temple of Preah Vihear, situated on their mutual border. Both sides claimed jurisdiction over the temple, which had been designated a UNESCO World Heritage site that year, and dispatched troops to the area. The impasse continued for several years, and tensions mounted over border incursions and other incidents. Attempts to mediate the disagreement failed, but, after skirmishes broke out there in 2011, Cambodia appealed to the International Court of Justice at The Hague to confirm a 1962 ruling made by that body in favour of Cambodia. The court initially called for all troops to be withdrawn from the area (which was done in 2012), and in 2013 it ruled that Cambodia should control the temple site.
