Jordan’s King Abdullah II has turned down attempts by Israeli Prime Minister Benjamin Netanyahu to speak over the phone, Palestinian agency Maan News reports, citing an unnamed Jordanian official.

King Abdullah has also refused to set a specific date for a future meeting with Netanyahu’s coalition partner, Benny Gantz, who is making overtures to coordinate Israel’s plans regarding the West Bank, according to the report.

King Abdullah said on many occasions that he would not accept the unilateral action by Israel and warned last month that it would trigger a “massive” confrontation with Jordan. He stopped short of outlining any specific steps, but said Jordan was “considering all options.”

Netanyahu has secured Gantz’s backing to apply Israeli sovereignty to 30 percent of the West Bank, including all Jewish settlements and the Jordan Valley bordering on the kingdom, starting from July 1.

Jordan is one of only two Arab countries that maintain official diplomatic relations with Israel, the other being Egypt.
