中国对一些美国产品征收关税（高达25％）
US President Trump increased the tariff on imported steel and aluminum from abroad earlier this month.
The BBC has said that China has imposed a duty on 128 products imported from the US, including pork and wine.
This tariff, effective from Monday, will affect the import of nearly three billion dollars
Beijing has said that this step has been taken for the protection and balance of the Chinese interests because of the loss of the US due to the new tariff imposed.
Earlier China had said that they do not want trade warfare, but they will not be sitting if their economy is damaged.
On the other hand, Trump called the trade war "good" and claimed that it would the 'easy' win for US.
The BBC's representative from Washington announced that the US authorities have already announced plans to impose more than $ 500 billion worth of imported Chinese products.
The US authorities are being harmed for unfair trade practices in China, which is why these steps have been taken by the US authorities.
But the possibility of more counter-measures has been increased in the wake of US action, and thus counterterrorism can become a trade war.
