Step-by-step explanation:
Liaoning province of Northeast China has the closest economic ties with Japan. This is evidenced by the impact that Japan, as an economic power in Asia, has on the region through its trade relations and investments. Northeast China, including Liaoning, benefits from industrial activities in the lower Liao River Basin and the Songhua River Basin, fostering strong industrial centers such as Harbin and Shenyang. Japan's search for cheap labor and advantageous trade conditions due to geographic proximity has made China an attractive destination for manufacturing ventures.
Historically, China and Japan have had a complex relationship, with Japan establishing a sphere of influence in the region following the lease of Port Arthur and further interactions during and after the colonial period. Despite Japan's past as a colonizer leading to strained cultural relations, the modern dynamics of economics often transcend political and historical challenges, leading to significant trade between China and Japan. Additionally, Japan's history of technological and economic development influenced by geographic location and cultural factors has similarities with other economically thriving Asian entities.
Therefore, amongst the choices provided, Japan has the strongest economic connection with Liaoning province, underpinning the significance of geographical location in shaping international economic relationships.
