Final answer:
China and Japan have in common a history of strong cultural traditions, thought they have also interacted with and adapted some foreign influences primarily to advance their economic and military agendas.
Step-by-step explanation:
Something China and Japan have in common is d. they have a history of strong cultural traditions. Both nations have a rich heritage of unique cultural practices and beliefs. For example, China's Confucianism has long been a cornerstone of its societal organization, while Japan's Shintoism and the samurai tradition showcase its distinct cultural identity. Despite periods where each country borrowed and adapted Western ideas, particularly in military and industrial domains, they have maintained core elements of their native traditions. Their industrialization did indeed contribute to their improved economies, mirroring paths taken by economic tigers like Hong Kong and Taiwan. Moreover, their histories reveal not only instances of adaptation but also periods of resistance to foreign influence, as seen in Japan's resentment towards Western powers post-World War I and measures taken by East Asian nations to limit the impact of contact with outsiders.
