Smartphone maker Samsung is halting shipments of its phones and chips to Russia “due to current geopolitical developments”.
The company said it will “continue to actively monitor this complex situation to determine our next steps”.
The South Korean electronics giant is the most popular smartphone brand in Russia, ahead of China’s Xiaomi and America’s Apple.
In addition to suspending sales, the company says it will also donate $6m (£4.5m) – including consumer electronics and voluntary donations from employees – to support humanitarian efforts in Ukraine.
Friday also marked other big exits, with Microsoft suspending sales of its products and services in Russia.
French luxury retailers LVMH, Hermes, Kering and Chanel said they would close their Russian stores, and Danish beer giant Carlsberg halted Russian exports and investments.
