History shows that the roots of Australia−Thailand relations were commercial roots, leading the
way by Trade and investment. When we take a closer look at the relationships between two
countries, they are rather complementary than to compete or to substitute. This is evidently in
manufacturing sector, agricultural sector, and investment sector. Therefore, this paper examines the
degree of complementarity of endowments between two countries in order to understand the
foundation of strategic relationships between Australia and Thailand. The paper is structured as
follows. Section 2 and 3 provides the characteristics and resource endowment of the two countries.
Section 4 illustrates trade and investment of Australia with reference to Thailand. Some general
conclusions are drawn in the final section.
