I don't think there will be trade wars, what's been happening around is the fear on China getting completely cashless in few years time. Now with the payments app alipay, tencent each and every form of payments were made without any intervention of banking bodies. When it comes to USA the same is being done through visa, and other payment processors along with banking system. In China most of the people even don't have a bank account. This cause a major loss in revenue to big giants and that pressure is getting reflected in such a way.
