ISLAMABAD/ RIYADH, July 17 (Reuters) - Pakistan has been negotiating an expanded defence pact with Kuwait in exchange for energy cooperation and investment, according to five sources with knowledge of the talks.
The talks remain at an early stage, all the sources said, and could still be complicated by heightened tensions between the United States and Iran, said one source.
