It depends on how intense the law/sanctions are. Example, no US company can trade/do business with Iran,even indirectly. The Trump administration also made it difficult for other countries to do business with Iran, makes it almost impossible for any other country to business with them.Hence, Iran's economy is in the toilet, and it can only trade with Russia, China and the middle eastern countries they have high-influence over(which are typically poor). Their oil can be sold to western countries, due to OPEC, but money that ends up in foreign accounts are inaccessible.

Plus, most of Trump's policies of late with China has to do with the new Silk Road. The new Silk Road is seeing China expand(land grabs) into other countries, and take over strategic points. Since, a lot of China's economy is from foreign trade, the more US makes trade difficult the harder it is for China to expand. Time, will tell if this strategy works or not, when China becomes the #1 superpower/economy in the world(speculation, but is looking more likely).
