Saudi King Salman has invited Qatar's emir to a meeting next week of the Gulf regional bloc in Riyadh, Qatari state media said Tuesday, without specifying if Doha had accepted.

The invitation to the December 10 summit of the six-nation Gulf Cooperation (GCC) comes amid signs of reduced animosity between Qatar and Saudi Arabia, which has led an economic boycott of Doha since 2017.

Saudi Arabia and allies Egypt, Bahrain and the United Arab Emirates closed their airspace to Qatar Airways and banned travel to the country over charges that Doha backs radical Islamists and seeks closer ties with Iran.

Qatar vehemently denies the charges.

The three Gulf boycott countries are currently participating in a regional football tournament in Qatar, having announced their participation at the last minute.

Saudi Arabia, which has also sealed its land-border with Qatar, will play the hosts at the semi-finals on Thursday.

"The emir, Sheikh Tamim bin Hamad Al-Thani, received a written message from... Saudi King Salman bin Abdulaziz Al-Saud to attend the (GCC) summit," the Qatar News Agency reported. The emir has been represented by senior officials at GCC summits since the blockade was imposed, despite having received invitations.

Regional analyst and King's College London assistant professor Andreas Krieg said he believed that Riyadh had pushed for the gathering to be shifted from the UAE to Saudi Arabia to increase the likelihood of the emir attending.

"Talks that have been held over the last couple of weeks, including the ones with the foreign minister, have centred on a lift of the blockade from the Saudi side," he said.

The Qatari Foreign Minister Mohammed bin Abdulrahman Al-Thani met with officials in Saudi for talks last month, according to an Arab diplomatic source.
