Tariffs are the word of the day, but "non-tariffs barriers" are among the reasons why China has been singled out for higher tariffs.
Since President Trump’s first term, the world’s two biggest economies have charged tariffs on more than half of what they sell each other.
However, American companies have long complained about the non-tariff barriers that make life difficult for them in China.
It means they can’t sell and operate as freely as many would like in a country with huge potential because of its sheer population size.
These restrictions can include a lack of protection for their intellectual property, which makes it hard to stop Chinese companies copying products.
There are also limits on what foreign companies can own in certain industries, and the question of whether the Chinese government gives unfair financial help to some of its companies to help them compete internationally. It’s often denied doing so.
Both the US and China have increased various economic restrictions, particularly on technology, in recent years. And President Trump’s newest tariffs mean a further decoupling is likely.
