China should learn from Japan in the 1980s, and never allow a trade war to become a currency war, says Sheng Songcheng, a senior adviser to the People’s Bank of China (PBOC).

The current trade spat between the two biggest economies is reminiscent of tensions between Japan and the U.S. in the 1980s, said Sheng, former head of the central bank’s Statistics and Analysis Department. The comments echo those from former Japanese central banker Kazumasa Iwata, who said Wednesday that China should be careful on the exchange rate issue. Japan signed the multilateral 1985 Plaza Accord to let the dollar weaken, but its exporters were hurt after the yen strengthened far more than anticipated, according to Iwata, who was a senior official at the time. That is a different situation than the one China faces now, which is whether it should unilaterally devalue its currency as a tool in a trade dispute with the U.S. But the warnings from Sheng and Iwata are essentially the same — don’t mix trade policy with currency or monetary policies. “Trade is trade, and it would be stupid to have a currency war which would make everybody around the world unhappy,” Sheng said in an interview in Boao, China, adding that a stable currency is better for China’s plan to upgrade its industrial base.
