In 1995, after Hamad bin Khalifa Al Thani deposed his father to become emir of Qatar, UAE granted asylum to the deposed Khalifa bin Hamad Al Thani in a quarters in Abu Dhabi. Sheikh  Zayed bin Sultan Al Nahyan tried to mediate between the father and his son, and advised Khalifa bin Hamad to congratulate his son. The coup affair was revived in 2018 after the Qatar diplomatic crisis with Al Jazeera broadcasting documentaries of new details accusing UAE, along with Saudi Arabia, Bahrain, and Egypt, of plotting to overthrow Hamad bin Khalifa Al Thani and reinstating his father Khalifa bin Hamad Al Thani. According to the documentary, a former French army commander Paul Barril was contracted and supplied with weapons by the UAE to carry out the coup operation in Qatar. UAE minister  of foreign affairs Anwar Gargash responded to the documentary and stated that Paul Barril was in fact a security agent of Sheikh Khalifa bin Hamad Al Thani who visited Abu Dhabi and had no relationship with the UAE and the documentary was a falsification to inculpate the UAE. 2014 Riyadh Agreement. The UAE, along with Saudi Arabia and Bahrain, withdrew their ambassador from Qatar in March 2014 due to alleged failure by Qatar to abide by an agreement not to interfere in the politics of these countries. The main reason for the dispute was UAE's support for the political  regime in Egypt led by Abdel Fattah el-Sisi and Egypt's military elite which contrasted Qatar's support for the democratically elected Muslim Brotherhood. The government of Qatar continued to back the Muslim Brotherhood in Egypt, and Qatar's emir Tamim bin Hamad Al Thani denounced el-Sisi's election as president in June 2014 as a ‘military coup’. The ambassadors returned to their posts in June. In September 2014, it was reported that the Emirati government invested $3 mn into a lobbying campaign against Qatar, primarily as a response to Qatar's support for the Muslim Brotherhood . The campaign was aimed at influencing American journalists to publish critical articles of Qatar's alleged funding of Islamist groups. Qatar has also been accused of influencing news outlets to report unfavorably on the UAE. It was claimed by journalist Brian Whitaker that the UAE used Global Network for Rights and Development, an NGO to which it has ties, as a political tool. Whitaker claimed that the organization showed favoritism in its 2014-human rights index by ranking UAE at 14 and Qatar at 97. The organization has also taken an opposing stance towards Qatar's hosting of the 2022  FIFA World Cup over human rights concerns. Two of the organization's employees were arrested by Qatari authorities in 2014 while they were investigating the living standards of foreign laborers. Second Libyan Civil War. The second Libyan Civil War has been described as a proxy conflict between the two countries, with the UAE backing the secular Tobruk government and Qatar backing the Islamist National Salvation Government. 2017–2021 Qatar diplomatic crisis. On 5 June 2017, the UAE, along with Saudi Arabia, Egypt and Bahrain, severed ties with Qatar, accusing it of supporting terrorism. This was precipitated by messages broadcast by the  Qatar News Agency in May 2017 which criticized Saudi Arabia and cast Iran and the Muslim Brotherhood in a positive light. Qatar denied that it was responsible for the messages, claiming that its news agency was hacked. The four aforementioned countries censored all Qatari news outlets as part of severing diplomatic ties. In addition to severing ties on 5 June, the UAE also expelled all Qatari nationals living in the Emirates and prohibited its citizens from travelling to Qatar. Furthermore, the UAE closed off its airspace and territorial waters to Qatari vessels. According to Islam Hassan, a research analyst in  Georgetown University in Qatar, "there has been always competition between al-Nahyans of Abu Dhabi and al-Thanis of Qatar. This competition goes back to the 1800s. The Arab uprisings ushered a new chapter in the Qatari–Emirati competition. The competition led to the Emiratis playing a major role in the withdrawal of ambassadors from Qatar in 2014. At the beginning of the current diplomatic crisis, particularly after the hacking saga, UAE was trying to maintain the problem. Yet, Al Jazeera's publishing of Yousuf al-Otaiba's leaked emails got the UAE on board with Saudi Arabia." In two  separate incidents, on 21 December 2017 and 3 January 2018, the UAE was accused by Qatar's government of infringing on its airspace with fighter jets. As a result, two complaints were filed to the UN by Qatar's representative Alya bint Ahmed Al Thani. For their part, the UAE rebuked the allegations, claiming that it had never impeached on Qatar's airspace with warplanes. On 14 January, Qatari Sheikh Abdullah bin Ali Al-Thani, reportedly released a video in which he claimed he was being detained in the UAE by Emirati authorities after being invited to the country by  Mohammed bin Zayed Al Nahyan. Emirati authorities denied that he was being forcefully held stating that he was in the country “at his own behest”. According to UAE authorities, "Sheikh Abdullah had expressed his desire to leave the UAE following which all measures were taken to honour his desire without any reservation". Another air traffic-related incident occurred on 15 January 2018, when the UAE accused Qatar of 'intercepting' two civilian airliners en route to Bahrain with fighter jets. This was quickly denied by Qatari government officials. During the 2019 Asian Cup semifinal match between Qatar and the tournament host  United Arab Emirates, the UAE supporters threw bottles and footwears into the pitch. This conduct was preceded by booing the Qatari national anthem. Qatar won 4–0 despite the situation, paving way to their first Asian Cup final and eventual title. On 12 November 2019, the UAE decided to participate in the 24th Arabian Gulf Cup, which is being hosted by Qatar, after boycotting it earlier. According to analysts, the participation from the UAE signaled that the feud between the countries might come to an end soon. On 6 January 2021, Qatar and UAE agreed to fully restore diplomatic ties.

The UAE denied that there are safety issues with the plant, which is being built by Korea Electric Power Corporation (KEPCO), and stated “The United Arab Emirates ... adheres to its commitment to the highest standards of nuclear safety, security and non-proliferation.”
