The Impact of Saudi Arabia's Potential Investment in Iran on Global Politics.

Saudi Arabia's Finance Minister Mohammed Al-Jadaan has said that the kingdom could start investing in Iran "very quickly" following a breakthrough agreement to re-establish diplomatic relations between the two countries. The countries have agreed to affirm "the respect for the sovereignty of states and the non-interference in internal affairs of states," a major step after years of mutual animosity, suspected attacks and espionage between the two countries. Investment from Saudi Arabia would likely be a major boon for Iran's battered economy, though it's unclear whether existing U.S. sanctions on Iran would apply to financial activity between the two countries.
