Qatar, which denies any support for extremists, has been defiant, saying it will not bow to pressure and that the demands seem created to be rejected.
Kaabi said there is no cooperation with Iran on any project in the North Field, but the countries have a joint committee that meets every year to discuss development of the field.
"This new project will strengthen Qatar's leading position and we will remain the leader of LNG for a very long time".
However, Saudi Arabia and its allies have threatened to sanction global firms working with Qatar if the tiny-Gulf nation fails to meet their demands.More news: Backed forces in Syria breach wall of Old City of Raqqa
"Qatar Petroleum will continue working.If some companies decide they don't want to work with QP that's their choice".
"We have absolutely no fear of having the embargo in place", he said.
"If there are no companies willing to work with us, we will do the 100 million tons", Al-Kaabi insisted. Al Kaabi said the force majeure declaration was imposed "illegally" on the condensate shipments.
Any measures that are taken will be "within the framework of worldwide law", Sheikh Abdullah said at a press conference in Abu Dhabi with German Foreign Minister Sigmar Gabriel, who was due to travel to Doha later Tuesday.More news: Boris Johnson joins call to end 1% public-sector pay cap
