Nearly a quarter of European firms in China are looking to invest elsewhere.

Good morning, Quartz readers!

Here’s what you need to know

Nearly one quarter of European firms in China are considering shifting investments elsewhere. Pandemic restrictions have disrupted business and generated uncertainty for European companies. Meanwhile, a covid-19 outbreak in Macau has shuttered shops—but not casinos.

Russia became China’s number one oil supplier. While Western buyers renounced Russian energy imports over the war in Ukraine, Chinese companies went on a shopping spree.

Rail workers in the UK are going on strike after negotiations failed. The walkout will be the biggest in 30 years, and severe service disruptions are expected today.

Primark opened up to e-commerce. The fast fashion retailer will trial a click and collect service in the UK, having previously shunned online sales.

A Chinese beach resort temporarily banned Tesla cars. The two-month restriction coincides with a secretive annual gathering of the country’s top leaders, Reuters first reported.

A Japanese court ruled the country’s same-sex marriage ban is constitutional. It’s the only G7 country that offers no legal recognition for LGBTQ couples.

What to watch for

A law giving the US enhanced powers to block the imports of goods tied to forced labor in China takes effect today. The Uyghur Forced Labor Prevention Act targets goods originating from the northern autonomous region of Xinjiang, a major manufacturing hub.

US legislators and governing bodies have stated the region is host to mass internment camps subjecting thousands of detainees from Muslim minorities to forced labor as well as other abuses. The Chinese government rebuffs the accusations and has cautioned against implementing the bill as it would disrupt business relations between the two countries.

These are some of the sectors most exposed to the risk of forced labor.

No one really wants ultra-fast food delivery

Ultra-fast delivery service, a business model that drew billions in investment during the pandemic, is now facing troubled waters in a post-pandemic world. Having burned through VC cash, and with customers once again free to roam, many delivery startups are cutting back their services or closing shop.

Others, like the US company Gopuff and Germany’s Gorillas, which operate in hundreds of cities, are using discounts to attract and retain customers as they seek to chart a course to profitability. But the high percentage of discounts is not a great sign for the industry, which has relied on scale and cheap services for cash flow.

With unstable markets and investors shifting to other prospects, delivery services will likely have to change their strategy if they want to stay afloat.
