During the 1950s and 1960s Japan, while neutral, grew rapidly by supplying American wars in Korea and Vietnam during the Cold War. The trade relationship has particularly prospered since then, with Japanese automobiles and consumer electronics being especially popular, and Japan became the world's second economic power after the United States. Despite now being allies, both Japan and the United States would come to a head once more, this time economically, with a trade war between the two countries during the late 1980s and early 1990s, which culminated after the Japanese asset price bubble burst shortly after the signing of the Plaza Accord. Japan would eventually drop to third place in 2010 after China.
