Qatar's foreign minister called on Thursday for the United Nations to help resolve the Gulf crisis and accused the four Arab countries that have imposed a blockade on Doha of violating international law.

Sheikh Mohammed bin Abdulrahman Al Thani told reporters that Saudi Arabia, the United Arab Emirates, Bahrain and Egypt are showing "stubbornness" and have not taken any steps to solve the crisis.

He vowed that Qatar would spare no effort to overcome what he called "violations" of international law and said, "the United Nations is the right platform to start from".

Mohammed bin Abdulrahman spoke to reporters after discussing the crisis with UN Secretary-General Antonio Guterres, who has supported regional efforts led by Kuwait to resolve the dispute.

"There is a role for the Security Council and for the General Assembly and all the United Nations mechanisms" in resolving the crisis, said Mohammed bin Abdulrahman, adding that he briefed council members on the dispute a month ago.

"The state of Qatar has already stated more than 10 times that we want to solve this issue by dialogue and we are not willing to escalate - and they need to retreat from all their illegal actions," Mohammed bin Abdulrahman said.

China's UN ambassador, Liu Jieyi, told reporters that the Security Council would take up the crisis if there is a formal request.

"I think it's something that should be sorted out among the brothers in the GCC and in the region," he said, referring to the Gulf Cooperation Council, which Saudi Arabia, UAE, Bahrain and Qatar belong to. "And I just hope there is a negotiation process for the various sides to sort out their difficulties."

'At a standstill'

In Washington, where Mohammed bin Abdulrahman met a day earlier with Secretary of State Rex Tillerson, State Department spokeswoman Heather Nauert said the crisis appeared to be "at a standstill."

"That naturally concerns us," Nauert said. "We are urging direct talks between all of the parties because we believe that in order for the situation to be resolved - and it does need to be resolved - they have to sit down together and have some direct dialogue."

However, UAE Ambassador to the UN Lana Nusseibeh said the measures taken were "entirely legal, justified and proportionate" and accused Qatar of grave violations.

"We hope to see a diplomatic solution at the regional level through genuine engagement from their side," she told Reuters.

Saudi Arabia, Egypt, the UAE, and Bahrain broke diplomatic relations with Qatar in early June largely over their allegations that it supports "terrorist" groups - a charge Qatar rejects.

They initially made 13 demands, which Qatar also dismissed.

Last week, the quartet urged Qatar to commit to six principles on combatting "extremism" and "terrorism" and negotiate a plan with specific measures to implement them.

Qatar's ruler has reiterated his country's willingness to fight "terrorism" and issued a decree revising the country's counterterrorism laws.

OPINION: The crisis of regional order in the Gulf

Qatari officials said the crisis was sparked by a cyberattack in May that they said was linked to the UAE. The UAE has denied any involvement.

The attack involved what Qatar says were fabricated comments attributed to the emir posted on the official state news agency's site and affiliated social media accounts in which he supposedly called Iran an "Islamic power" and said Qatar's relations with Israel are "good".

Qatar swiftly disavowed the comments but state-owned and semi-official media in Saudi Arabia, the UAE and Bahrain continued to report the remarks for days.

Mohammed bin Abdulrahman told reporters on Thursday that "the entire crisis has been based on a fragile foundation, which is a cyberattack, which is considered an electronic terrorism against the state of Qatar".

Imad Harb, Director of Research and Analysis at the Arab Center Washington DC, told Al Jazeera he does not think the crisis will end soon.

"And it's not ending because it can't be resolved - it can be resolved," he said.

"The biggest problem is that the countries that have started this whole thing have really painted themselves into a corner from which they just simply cannot withdraw."
