The South Korean tech giant is the world's biggest memory
chip maker and the leading smartphone seller in Russia.
"Due to current geopolitical developments, shipments to
Russia have been suspended," Samsung said in a statement.
"We continue to actively monitor this complex situation
to determine our next steps."
The decision comes as Western governments, sporting
organisations and big companies cut Russia off and deal it punishing sanctions
over the internationally condemned attack on its neighbour.
Samsung controls just above 30 percent of the smartphone
market share in Russia, according to Bloomberg News — four percent of the tech
giant's total global smartphone revenues.
Sales of semiconductors in Russia, in turn, accounted for
less than 0.1 percent of Samsung's profits, according to a report by Hana
Financial Investment.
South Korea, a key US security ally, also this week
announced it would block financial transactions with major Russian banks and
their subsidiaries subject to US sanctions.
Samsung is also donating $6 million, including $1 million in
consumer electronics as well as voluntary donations from employees, to
"actively support humanitarian efforts" and refugees in the region,
the firm said.
