Pakistan, Saudi Arabia and Turkey have prepared a draft defence agreement after nearly a year of talks, Pakistan's Minister for Defence Production said, a signal they could be seeking a bulwark against a flare-up of regional violence in the last two years. Raza Hayat Harraj told Reuters on Wednesday the potential deal between the three regional powers was separate from a bilateral Saudi-Pakistani accord announced last year. A final consensus between the three states is needed to complete the deal, he said.
