There is a long history of the bilateral relations between Thailand and China, economically, politically, and socially. Since 1975, the ties have been developing in a sound and stable manner over the past 44 years. High ranking leaders of Thailand and China frequently visit each other and have great affections for each other. His Majesty the King, Her Royal Highness Princess Maha Chakri Sirindhorn and other Royal Family members have visited China several times. Both Thailand and China admire their long history and shared culture and thus enjoy great potential for people-to-people and cultural exchanges.Both countries benefited from rapid economic, trade, and investment expansions. Currently, China is the largest trading partner of Thailand, both in terms of the largest export market and also the largest import source and the Chinese are the largest tourist group of Thailand with about 10 million Chinese tourists visiting Thailand each year.Thailand-China relationship has set a good example for relationships between good neighboring countries. Even though at times, Thailand would face political changes, it continuously kept close ties with China. The Thai government viewed it as highly important to strengthen economic ties as well as trade and investment relations between Thailand and China. Therefore, Thailand-China friendship relations could be viewed as a good model by co-existing in harmony and pursuing joint development of two different political systems.However, both Thailand and China are recently faced with an increasingly uncertain and unstable world, especially with disruptive technologies and undergoing major economic transformation and adjustment.The two counties need to develop their relations into a new chapter, especially in terms of upgraded economic ties. In addition, given its strategic location at the heart of mainland Southeast Asia and status as the region’s second-largest economy, Thailand can play an important role in and gain potential benefits from linking its new economic model of Thailand 4.0 with China’s Belt and Road Initiative (BRI).
