Last week, Saudi Arabia, the United Arab Emirates, Egypt and Bahrain led a string of countries that cut ties with Qatar over what they say is the emirate's financing of extremist groups and its ties to Iran, Saudi Arabia's regional arch-rival.
"Qatar Petroleum... is conducting business as usual throughout all its upstream, midstream and downstream businesses and operations, and in all activities across all of QP's world-class facilities", a statement read.
"The citizens of these states have absolute freedom to stay in the territories of the state of Qatar in adherence with the laws and applicable regulations in the country in the context of working treaties established with them and with the agreement of their countries and based on entry visas that are available to them" it continued.
Federation Internationale de Football Association president Gianni Infantino today said he was confident the diplomatic crisis posed no threat to the 2022 edition of the World Cup, which raked in United States dollars 4.8 billion in 2014 in Brazil, according to a Federation Internationale de Football Association report.
"Following the sanctions. on Qatar, IranAir has so far transported food and vegetables to this country by four flights", Shahrokh Noushabadi, head of public relations at Iran's national airline, was quoted as saying by Fars news agency.
Riyadh and its allies have severed ties with Qatar, accusing it of supporting terrorism and of being too close to Iran, charges denied by Doha.
Iran said the planes were filled with vegetables and that it plans to send 100 tons of fresh fruit and legumes every day to the import-dependent nation, according to the semi-official Tasnim news agency.
"We will continue deliveries as long as there is demand", Noushabadi added, without saying if the deliveries were commercial exports or aid. Qataris have been ordered to leave some of the blockading nations, but Qatar has said it will not follow suit.
Qatar has expressed readiness "to understand the concerns of its brothers and respond to the efforts of the emir (of Kuwait) to strengthen peace and security", the foreign minister said.
Saudi Arabia said today it was ordering "suitable measures" to help families with mixed citizenships but provided few details.
But the UAE said it drew a distinction between Qatar's government and its people.
