U.S. President Donald Trump's abrupt declaration that Washington will recognize Israel's sovereignty over the disputed Golan Heights drew strong condemnation from Syria, while the European Union and countries like Egypt and Russia also rejected the overture.

The Syrian government called it "irresponsible," and a threat to international peace and stability. The Foreign Ministry in Damascus also said Syria is now more intent on liberating the Golan, "using every possible means."

The Foreign Ministry in Damascus said Trump's statement confirms "the blind bias of the United States to the Zionist entity," referring to Israel, and added that it won't change "the fact that the Golan was and will remain Arab and Syrian."

The EU reiterated on Friday its position "has not changed" despite Trump's overture.

"The European Union, in line with international law, does not recognize Israel's sovereignty over the territories occupied by Israel since June 1967, including the Golan Heights and does not consider them to be part of Israel's territory," an EU spokesperson told Reuters.

Trump's administration has been considering recognizing Israel's sovereignty over the Golan, which Israel captured from Syria in the 1967 Arab-Israeli war. Last week, in its annual human rights report, the State Department dropped the phrase "Israeli occupied" from the Golan Heights section, instead calling it "Israeli controlled."

Announcement could give Netanyahu a boost

A senior administration official told Reuters on Friday that U.S. officials are preparing a document to codify recognition of Israeli sovereignty of the Golan Heights. The official added that Trump is likely to sign the presidential document when Israeli Prime Minister Benjamin Netanyahu visits Washington next week.

Trump's announcement marked a major shift in American policy and gives Netanyahu a political boost a month before what is expected to be a close election.

Against this backdrop of hostility towards the U.S. move, Secretary of State Mike Pompeo landed in Beirut after visiting Israel on Friday. He is expected to pile pressure on the government to curb the influence of the Iran-backed Hezbollah.

The declaration is the latest in a series of moves that have fuelled anger among Israel's Arab enemies and U.S.-allied Arabs.

It follows the U.S. recognition in December 2017 of Jerusalem as Israel's capital — a decision that also drew international criticism as the disputed city's status remains at the heart of the Israel-Palestinian conflict.

Canada, other countries weigh in

In a statement released Friday, a spokesperson for Global Affairs Canada said the country's policy on the Golan Heights has not changed.

"Canada's long-standing policy is that it does not recognize permanent Israeli control over territories occupied in 1967, including the Golan Heights," Stefano Maron said in an email to CBC News. "That has been Canada's long-standing and consistent position."

Canada ended a 32-year peacekeeping mission in the Golan Heights in 2006.

Egypt said it considers the Golan Heights as occupied Syrian land; in a statement carried by state news agency MENA, the Egyptian Foreign Ministry cited UN Security Council resolution 497 of 1981 that rejected Israel's annexation of the territory.

The ministry "stressed the importance that everybody should respect the resolutions of international legitimacy and the United Nations Charter in respect of the inadmissibility of acquiring land by force," the statement said.

Israel captured much of the Golan from Syria in a 1967 war and annexed it, a move not endorsed internationally. Netanyahu raised the possibility of U.S. recognition in his first White House meeting with Trump in February 2017.

A Golan Heights force was set up after the 1973 Arab-Israeli war to monitor the ceasefire. Much of the world, including Canada, recognizes the Golan Heights as occupied territory.

France's Foreign Ministry said recognition of Israel's annexation is contrary to international law. "The Golan is a territory occupied by Israel since 1967. France does not recognize the Israeli annexation of 1981," the ministry said in a daily briefing.

"The recognition of Israeli sovereignty over the Golan, occupied territory, would be contrary to international law, in particular the obligation for states not to recognize an illegal situation," the ministry also said.

Netanyahu faces an election on April 9 and has been pressing for the United States to recognize Israel's claim to sovereignty over the Golan Heights.

Trump remains popular in Israel, and his advisers have been developing a Middle East peace proposal for release sometime after the Israeli elections. Netanyahu tweeted his gratitude.

Russia, an ally of President Bashar al-Assad with forces in Syria, said Trump's comments risked seriously destabilizing the region and expressed hope the statement was just declaratory.

Kremlin spokesman Dmitry Peskov told reporters that Trump's comments "can destabilize the already fragile situation in the Middle East."

"The very idea is not helping the goals of the Middle East settlement, quite the other way round," he said. "Right now, it's merely a declaration. Let's hope it will stay this way."

Iran, Turkey criticize U.S. move

Iran, Assad's main regional ally and which also has forces in Syria, condemned the statement as illegal and unacceptable.

Turkey, a U.S.-allied state and an adversary of Damascus, also criticized the move, saying it had brought the Middle East to the edge of a new crisis and the legitimisation of the occupation of the Golan Heights could not be allowed.

Syria's Foreign Ministry later announced that a letter was sent to the presidents of the UN Security Council and United Nations over Trump's "irresponsible and dangerous statements over the Golan." The statement urged the UN secretary-general to confirm the organization's stance regarding Israeli occupation of the Golan.

In a Friday tweet, Iranian Foreign Minister Javad Zarif took aim at the U.S.

US is the single biggest source of instability in MidEast. It may be deluded enough to believe that persistently violating int'l law, bullying sovereign nations & milking its clients projects strength. It does not. Its recklessness just displays panic of an empire in decline. —@JZarif

Arab League chief Ahmed Aboul Gheit also criticized the American stance, saying it "comes outside the international legitimacy and no country, no matter how important it is, can make such a decision."

Turkish President Recep Tayyip Erdogan said Trump's "unfortunate" declaration has brought the region "to the brink of a new crisis and new tensions."

"We will never allow the legitimization of the occupation of the Golan Heights," Erdogan added.
