Take, for example, the recent mending of relations between Saudi Arabia and formerly bitter adversaries Iran and Syria. A China-brokered deal between the Saudis and Iran has them re-establishing full diplomatic relations, with the foreign ministers of both countries meeting in Beijing last week. It is the highest level meeting between the two countries in seven years.

Additionally, Riyadh is expected to invite Syria back into the Arab League and Syrian president Assad may attend the next Arab League summit. Syria was suspended from the Arab League 12 years ago when then-US allies in the Middle East signed on to Washington's "Assad must go" policy that wreaked havoc across the region.

And the nearly decade-long war in Yemen, which has devastated that population, appears to finally be ending, as Saudi Arabia is expected to announce an end to its US-backed war on that country. Troops from the United Arab Emirates are leaving Yemen and a Saudi delegation is arriving to negotiate a peace deal.
