Answer:
Japan
Step-by-step explanation:
Australia-Japan relations have elements of tension, as well as the recognized reciprocity of strong common interests and beliefs. Memories of World War II persist among the senior members of Australian public opinion, as does the current fear of Japanese economic domination in both countries, especially in Australia, despite these fears have fallen in response to economic stagnation of Japan in the 1990s. At the same time, government and business leaders see Japan as a major export market and an essential element in the strong growth in Australia's future and prosperity in Asia Pacific. It should also be noted that in 2007 both nations signed a mutual defense agreement, which aims to maintain peace between countries and protect each other from attacks that include a third nation.
