European shares dipped to their lowest in almost a month on Monday and world stocks followed as building deflationary pressure in China added to growth worries from a lacklustre U.S. economy and an escalating global trade war.

The leaders of both Canada and Mexico got on the phone with President Donald Trump this past week to seek solutions after he slapped tariffs on their countries, but China’s president appears unlikely to make a similar call soon.

As U.S. and Ukrainian officials prepare to meet in Saudi Arabia this week, President Donald Trump has privately made clear to aides that a signed minerals deal between Washington and Kyiv won’t be enough to restart aid and intelligence sharing with the war-torn country, according an administration official and another U.S. official.

National Economic Council director Kevin Hassett said in an interview with ABC News' "This Week" that the tariffs are not meant to start a trade war. "What happened was that we launched a drug war, not a trade war, and it was part of the negotiation to get Canada and Mexico to stop shipping fentanyl across our borders," Hassett said.

Korva herself didn’t want to talk politics with a Free Press reporter who had come to Windsor to gauge the mood in the city, but her comments shared one of the sentiments that was heard throughout the day: that people in the Windsor and Detroit areas are close, like family. Consternation at recent events was another.

The tariff war is a hot topic worldwide, especially after Trump imposed tariffs on Canada, Mexico, and China. However, China is expected to suffer the most from this decision, as it is known as the global manufacturing hub.
