Saudi Arabia has reopened its land border with Qatar, and Kuwait’s foreign minister has said the kingdom’s airspace and sea border will open too, before the Gulf Cooperation Council summit that is set to take place in Saudi’s Al-Ula province on Tuesday, an important step that could pave the way towards resolving a political dispute that led Riyadh and its allies to impose a boycott on Qatar more than three years ago. In remarks carried by the Saudi state-run news agency on Monday, Saudi Crown Prince Mohammed bin Salman said the GCC summit will be “inclusive”, leading the states toward “reunification and solidarity in facing the challenges of [the] region”.
