Erdogan's defense of Qatar, in a parliamentary speech to members of his ruling AK Party, comes after Saudi Arabia, the United Arab Emirates (UAE), Bahrain and Egypt severed relations with Doha last week, accusing it of supporting Islamist militants and Iran - allegations it says are baseless. Qatar has denied those charges.
According to sources, the premier and Army Chief will meet Saudi rulers in an effort to mediate between Saudi Arabia and Qatar.
Pakistan has close ties with the kingdom but also business ventures in Qatar.
Qatar's Foreign Minister Mohammed bin Abdulrahman Al Thani said Monday that the country's government still has "no clue what are the main reasons behind all these measures".
Speaking after diplomatic meetings in Paris, Thani said Qatar was ready to negotiate anything "related to the collective security of the [Persian] Gulf countries" but insisted that Qatari foreign policy was not open to debate. Taking in to account the Turkish Airlines A330 cargo aircraft load-carrying capacity of 65 tons, it is claimed that nearly a ton of foodstuff was shipped to Qatar from Turkey. And the Gulf countries were the centre of stability for that region.
As part of Qatar's efforts to de-escalate the tension, Qatari delegation today held talks with the Ethiopian Prime Minister, Hailemariam Desalegn, only a day after Saudi officials paid visit a to Addis Ababa on partly the same mission.More news: Global shares fall on Fed rate hike, UK rate outlook

Saudi Arabia has closed Qatar's sole land border and joined other countries in cutting off sea traffic, leading panicked residents to stockpile food.
Saudi Arabia, the UAE and Bahrain have taken into account the Saudi-Qatari families that extend from the Qatari people to the people of these three countries.
These policies helped the region's largest airlines - Emirates, Etihad Airways and Qatar Airways - to develop their home airports as hubs linking long-distance travellers. Qatar, which has yet to retaliate in the crisis, also could turn off supplies to those now opposing it as well, especially the United Arab Emirates, home to Dubai.
A senior Palestinian journalist said Monday the Qataris' "strong solidarity" had managed to keep the country's economy stable, despite the ongoing boycott by several Gulf countries.
They added that Qatar ignored repeated calls to abide by the Riyadh Agreement of 2013, its executive mechanism, and the supplementary agreement in 2014.
