FNA - Iranian Foreign Ministry Spokesman Seyed Abbas Mousavi blasted South Korea for blocking Iran's assets, stressing that Tehran is waiting for Seoul's tangible moves to return the funds.

Mousavi said on Wednesday that Iran has had enough of various promises made in South Korea about returning the funds that have been illegally blocked by two banks over US sanctions.

�We've much heard promises from South Korea. Now, we only wait for tangible, vital action,� he wrote on his twitter page.

The spokesman further warned Seoul that sending a large shipment of humanitarian goods to Iran paid for by Iranian funds would not please Tehran.

�We hope (South Korea) officials to remember aboutt amount of Iranian nation's financial resources in Seoul,� he said.

Reports in recent weeks had suggested that South Korea plans to allow Iran to use part of its funds, believed to be between $6 billion and $9 billion, to buy medicine and medical equipment from South Korean companies.

Trade sources have expressed hope that Iran could gradually use the funds for other purchases in South Korea in the near future.
