Ukraine and Saudi Arabia are preparing to sign an agreement on cooperation in the field of defense, Ukrainian President Petro Poroshenko has said.

"We have actually finished the discussion and are ready to sign an agreement on cooperation in the field of defense. I can say that two extremely important large contracts in the field of military and technical cooperation are being implemented," Poroshenko said.

He also noted that Ukraine and Saudi Arabia "demonstrate significant progress" in aircraft engineering.

"Our Antonov 132D aircraft is now in Saudi Arabia. And we are developing not a test model of the aircraft, but already the aircraft which will be in serial production. And we will consider expanding the range of aircraft that will be produced for Saudi Arabia at the first stage and produced in Saudi Arabia in the framework of... cooperation in the future," Poroshenko said.
