IRNA writes: Holding bilateral negotiations as well as announcements by Iranian officials are some of the signs showing that relations are getting improved between Tehran and Riyadh. The two sides cut their ties in 2016. The relations remained severed until last year when Donald Trump was defeated in US presidential election by Joe Biden. After Biden took over the White House in January this year, he made changes in US Mideast policies, including cutting the number of American military forces in West Asia. With these changes happening and progress being made in talks over the revival of the 2015 Iran nuclear deal, Saudi officials changed course too.
