1. China, Canada hit U.S. back with tariffs after Trump’s take effect

The U.S. tariffed $525B of Chinese exports in Feb. and Mar. rounds, while China targeted $36B of U.S. imports:

Bloomberg, China Customs.

  • 15% of tariffs imposed by China on U.S. agricultural goods.

  • China also banned exports to some defense companies.

  • Mon.: Trump proceeded with the 25% tariffs on Canada and Mexico and doubled tariffs on China to 20%.

  • Canada announced phased levies on $107B worth of U.S. goods.

  • Would await Trump’s decision before reacting, Mexican President Sheinbaum said.

The S&P 500 was -2% on Trump’s tariff move, marking the worst selloff of 2025

  • NVIDIA shares -9% on tariff fears.

2. Temu vs. Amazon: Who’s winning the price war?*

Omnisend

When it comes to online shopping, two names dominate the battlefield — Temu and Amazon. But what really sets them apart? Omnisend dug into the data, analyzing product listings, pricing tactics, and consumer trust on both platforms.

As a result, they’ve compiled a fascinating look into fierce competition, eyebrow-raising discounts, and growing concerns over brand imitation and fake reviews.

Here’s a glimpse of what they found:

  • Temu undercuts Amazon on price: Close product matches are 40% cheaper on average, saving shoppers around $13.37 per item

  • Product overlap is huge: 77% of Amazon-listed products have close equivalents on Temu, and one in 10 are identical

  • Brand imitation raises red flags: From blurred logos to copycat packaging, Temu products often mimic well-known brands

  • Discounts run deep: Temu’s slashing prices with up to 98% off in some categories, compared to Amazon’s 67% max discounts

  • Trust gap is real: Amazon’s review system is robust (50,000 reviews per product on average), while Temu trails behind with just 1,500, plus signs of potential review manipulation

So, who’s really winning — and at what cost?
