When traffic at a busy border crossing froze for a few days, it offered a glimpse into how businesses respond to new trade barriers.

President Donald Trump is preparing to announce a sweeping round of new tariffs on imports set to take effect Wednesday, which he has dubbed “Liberation Day.” Details of what could amount to a major escalation in Trump’s global trade war are expected to be released in the coming days.

Brazil's President Luiz Inácio Lula da Silva will meet with Russia’s Vladimir Putin in Moscow and China’s Xi Jinping in Beijing, two important partners for the South American giant, in May. The announcement Monday came as the world braces for a global trade war following U.

The Trump administration has discussed providing financial aid for farmers who may be subject to retaliation by America’s trading partners.

The EU has already announced that, if Trump’s trade war continues, the bloc will implement coordinated punitive tariffs targeting the American economy. Canada also has a plan to target industries in relatively Republican states, such as Harley-Davidson in Wisconsin or bourbon in Kentucky.

Air Canada says demand for flights between Canadian and US cities is weak for the spring and summer months, as Canadians respond to the trade war by avoiding trips south.

Some brewers have also lost access to store shelves from one big customer: Canada, which is the top foreign market for U.S. craft beer, accounting for almost 38% of exports. But Canadians are furious that Trump targeted their products, and Canadian importers have been cancelling orders and pulling U.S. beer off store shelves.

France still hopes Europe will avoid a trade war with the United States but it would reply with reciprocal measures if tariffs announced by U.S. President Donald Trump went ahead on Wednesday, said commerce and trade minister Laurent Saint-Martin.
