The Economist asks
When will Saudi Arabia announce the reopening of its land border with Qatar?
Temporary reopenings will not suffice (e.g., The Guardian). On 5 June 2017, Saudi Arabia, Bahrain, and the UAE cut diplomatic relations with Qatar, embargoing goods, closing borders, and requiring Qatari citizens to leave their countries (BBC, The Cipher Brief).
