President Donald Trump has moved to escalate a trade war, seeking to block imports of certain autos, dairy products, and alcohol. This action is in response to retaliatory tariffs imposed by Canada. The tariffs took effect earlier, prompting the US to take action.

The ban on Canadian alcohol imports is similar to earlier bans imposed by Canadian provinces on American alcohol. The US measures were signed into law under the Tariff Act of 1930.

Further details on the trade dispute and the measures implemented by the US are available, including documents posted by the White House.
