McDonald's, Starbucks, Coca-Cola, PepsiCo and General Electric ― ubiquitous global brands and symbols of U.S. corporate might ― all announced Tuesday they were temporarily suspending their business in Russia in response to the country's invasion of Ukraine.

''Our values mean we cannot ignore the needless human suffering unfolding in Ukraine,'' McDonald's President and CEO Chris Kempczinski said in an open letter to employees.

The Chicago-based burger giant said it will temporarily close 850 stores but continue paying its 62,000 employees in Russia ''who have poured their heart and soul into our McDonald's brand.''

Kempczinski said it's impossible to know when the company will be able to reopen its stores.

''The situation is extraordinarily challenging for a global brand like ours, and there are many considerations,'' Kempczinski wrote in the letter. McDonald's works with hundreds of Russian suppliers, for example, and serves millions of customers each day.

Last Friday, Starbucks had said that it was donating profits from its 130 Russian stores ― owned and operated by Kuwait-based franchisee Alshaya Group ― to humanitarian relief efforts in Ukraine. But on Tuesday, the company changed course and said it would temporarily close those stores. Alshaya Group will continue to pay Starbucks' 2,000 Russian employees, Starbucks President and CEO Kevin Johnson said in an open letter to employees.

''Through this dynamic situation, we will continue to make decisions that are true to our mission and values and communicate with transparency,'' Johnson wrote.

Coca-Cola announced it was suspending its business in Russia, but it offered few details. Coke's partner, Switzerland-based Coca-Cola Hellenic Bottling, owns 10 bottling plants in Russia, which is its largest market. Coke has a 21% stake in Coca-Cola Hellenic Bottling.

PepsiCo and General Electric both announced partial shutdowns of their Russian business.

Pepsi, based in Purchase, New York, said it will suspend sales of beverages in Russia. It will also suspend any capital investments and promotional activities.

But the company said it will continue to produce milk, baby formula and baby food, in part to continue supporting its 20,000 Russian employees and the 40,000 Russian agricultural workers who are part of its supply chain.
