Whether the China-US trade war will break out is an intriguing question for the world. The Conference Board, a renowned research group organization based in New York, has conducted research using export data, which shows the added value of the American and EU exports to China contribute the countries' economy output by 0.7% and 1.6 % respectively; even China’s neighbor Japan only scored 2.1 %. The added value of the Chinese exports to America contributed almost 3% of its GDP, indicating China will sustain more lost in the event of Sino-US trade war.
