Iran's economy minister says his country is seeking $45 billion in foreign investment following the implementation of a landmark nuclear deal with world powers last month.

Ali Tayebnia told reporters Saturday that Iran expects $15 billion in direct foreign investment alone in the next Iranian calendar that begins March 20.

The historic agreement brought about the lifting of international sanctions last month after the U.N. certified that Iran has met all its commitments to curb its nuclear activities under last summer's accord.

Iran expects an economic breakthrough after the lifting of sanctions, which will allow it to access overseas assets and sell crude oil more freely.
