The Greek government says Prime Minister George Papandreou is to meet the ruler of Qatar to sign an investment agreement.
A government statement says the meeting between the premier and Sheikh Hamad Bin Khalifa Al Thani is expected to start early Saturday evening. Other Qatari officials also will be present.
The statement does not specify the nature of the agreement, but state TV NET said it would be "an investment in northern Greece."
The deal comes as Greece, which is surviving on international loans, is trying to avoid default on its debt.
Qatar had previously expressed interest in the residential and commercial development of the former Athens airport and in a cargo port terminal in western Greece.
The cargo port terminal investment fell through, while the airport project has stalled.
