Thailand, a country located in Southeast Asia, is bordered by Myanmar to the north and northwest, Lao PDR and Cambodia to the east, Malaysia and the Gulf of Thailand to the south, and the Andaman Sea to the southwest. A unified Thai kingdom was established in the mid-14th century. Known originally as Siam, the country was renamed Thailand (Land of the Free) in 1939. Thailand's capital city is Bangkok, its currency is the baht (THB), and the official language is Thai.

Thailand is Southeast Asia’s second largest economy after Indonesia. With a well-developed infrastructure, a free-enterprise economy, and generally pro-investment policies, Thailand historically has had a strong economy. However, since 2019, the economy has declined due to weaker demand for exports reflecting the impact of US-China trade tensions, slowing public investments and a drought, impacting agricultural production. The growth rate for 2019 was 2.4%, down from 4.21% in 2018. In 2020, the Thai economy declined by 6.1% due largely to the impact of the Covid-19 pandemic both locally and globally. While increases were seen in the manufacturing, construction, agriculture and financial sectors, severe decreases were encountered in the accommodation, transport, wholesale and retail sectors. For 2021, the current expectation is an increase of 1.5-2.5% based on a significant recovery in the global economy, government expenditure, improvements in domestic demand and the low growth base in 2020.
