The benefits Mitsubishi had seen because of its strong presence in south-east Asia reversed themselves as a result of the economic crisis in the region which began in 1991 with the advent of the collapse of the Japanese asset price bubble, referred to in Japan as the beginning of the Lost Decade and continued to 1997. The collapse was partly the result of the Plaza Accord agreement in 1985, which sought to equalize the United States dollar with the Japanese yen and the German mark. In September of that year the company closed its Thai factory in response to a crash in the country's currency and plummeting consumer demand.
