The meeting between Trump and Chinese officials in Switzerland indicates a willingness to cooperate and reset relations, which could lead to increased trade and investment between the two countries. Historically, positive developments in US-China trade relations have boosted stock markets, particularly in industries that rely heavily on international trade, such as technology and manufacturing. The statement 'a total reset negotiated in a friendly, but constructive, manner' suggests a significant breakthrough, which could lead to increased market confidence and a decrease in volatility. Additionally, Trump's emphasis on 'an opening up of China to American business' could lead to new opportunities for US companies, potentially driving growth and investment. However, the sustainability of this progress remains to be seen, and investors will be watching closely for concrete actions and policy changes to support this reset.
