The prices of almost all commodity futures fell on the stock exchanges in China today. There are two reasons for this: 1.) The goal of economic growth was lowered at the People's Congress started today and 2.) The announcement of a security law for the government in Hong Kong.
Even while the political leadership in Beijing was giving speeches, prices on the stock exchanges dropped. Market participants are uncertain about the consequences that the increasing tensions between the USA and China will have for the economy.
