China issued a warning on Tuesday night that it stands ready for any "type of war" with the United States in the aftermath of tariffs imposed hours earlier by the Trump administration. A spokesperson for the Chinese foreign ministry said the tariffs would not lead to a resolution of U.

The Kremlin said on Monday that someone would have to force Volodymyr Zelenskiy to make peace and that the Ukrainian leader's public clash with U.S. President Donald Trump had shown just how hard it would be to find a way to end the war.

President Trump has doubled tariffs on China to 20% and confirmed 25% duties on imports from Mexico and Canada, citing fentanyl trafficking and trade imbalances.

The nation’s top three trading partners are rolling out levies on a wide range of products, including soybeans, meat and grains, in the escalating trade war.

The decrease in fentanyl overdoses, drug policy experts have said, has more to do with public health measures than changes in border policies.

If tariffs are a poor method of collecting revenue or strengthening trade, they're even less effective at stopping the flow of illegal drugs.
