Arab governments denounce Israel’s plans to annex the West Bank, warning it will imperil regional security and peace building. [washington post]

UAE Ambassador to the U.S. Yousef Al Otaiba warned Israelis that annexation would harm Israel-Gulf relations. "Annexation will certainly and immediately upend Israeli aspirations for improved security, economic and cultural ties with the Arab world and with UAE," he wrote.

Qatari authorities also threatened to stop aid to the Gaza Strip if Israel goes ahead with the annexation.

As significant as the Emirati and Qatari concerns are (Bahrain, Kuwait and Oman also have condemned Israel's annexation plan), it is the Saudi attitude that matters the most. The kingdom commands the Gulf Arab pack. No GCC country will seriously contemplate normalizing ties with Israel unless Saudi Arabia does it first. And the Saudis, who have officially condemned the annexation plan as well, are nowhere close to that prospect. [NPR]
