The Geographical Simulation Model of the Institute of Developing Economies (IDE-GSM) estimates the following economic impact of the US-China trade war: ?0.4% (of GDP) for the US, ?0.5% for China, and +0.1% for East Asia (excluding China). Moreover, the electronics and electrical machinery sectors in both the US and China will suffer significantly. By contrast, the electronics and electrical machinery sectors in East Asia could benefit from this trade war. Although the US-China trade war benefits East Asian countries, for the time being, they are more vulnerable to US tariff increases than China, and it would be preferable to bring the US back into multilateral trade negotiations in a concerted effort.
