"Ikhwan al-Muslimun doesn't recognize the endorsed contracts with the Zionist regime," Hamza Mansour, the secretary-General of Jabhat al-Amal al-Islami, a political offshoot of Jordan's Ikhwan al-Muslimun, was quoted as saying by Sharq news website on Sunday.
US Ambassador to Amman Stewart Jones had earlier declared that if Jordan's Ikhwan al-Muslimun remained committed to the agreements inked with Israel in the past, he would be ready meet with the party's leaders but the Muslim Brotherhood rejected the offer.
Meantime, different Jordanian cities were the scenes of huge protest rallies on Friday to call on the government to fight the existing corruption and implement reforms in the country.
The rallies were organized by Ikhwan al-Muslimun.
Pro-democracy activists have called for constitutional reform that would transfer the monarch's authority, to appoint and dismiss governments, to the parliament.
