Sweden and other European countries must be prepared for ongoing support and weapons deliveries to Ukraine as it faces a long-running conflict with Russia, Sweden's Defence Minister Peter Hultqvist said on Friday.

Sweden is seeking NATO membership as the conflict in Ukraine changes Scandinavia's security landscape, and on Thursday it announced it was providing Ukraine with more economic aid and military equipment, including anti-ship missiles, rifles and anti-tank weapons.

The military aid was the third package Sweden has provided to Ukraine since Russia invaded in February, although Hultqvist declined to comment on further aid being planned.

"I see this conflict as a long-running conflict," he told reporters on the sidelines of the GLOBSEC 2022 Bratislava Forum, a foreign policy gathering.

"We must be sustainable in deliveries, so we can come back with more later on. Different countries must be complementary to each other."
