For nearly two decades of the first century, the international community has been witnessing the continuous and strong development of relations between the Kingdom of Thailand and the People's Republic of China. Thanks to the development in political relations, other areas of cooperation in relations between Thailand and China have also developed rapidly, gaining many practical results. What strategy has Thailand chosen to develop such relations with China so quickly and extensively? To implement that strategy, what has Thailand been doing? How does the strategy that Thailand has chosen affect the security and development of Thailand, China, Asean-China relations and other international relations in Southeast Asia? The book described by the author based on honest and objective scientific research results with a close and easy-to-understand style.
