The United States has penned a deal with Qatar to sell F-15 fighters jets which is set to be worth more than NZD$16 billion.
The agreement comes after Trump criticised the oil-rich Gulf nation for supporting terrorism, and accused it of potentially interfering with the US State Department's influence to halt conflict in the region between other Arab countries.
The purchase was made in Washington DC as Qatar's Defence Minister was meeting with US officials, according to CBS.
"We are pleased to announce today the signing of the letter of offer and acceptance for the purchase of the F-15QA fighter jets, with an initial cost of (US) $12 billion dollars," Qatari Defence Minister Khalid al-Attiyah said in a statement.
"We believe that this agreement will propel Qatar's ability to provide for its own security while also reducing the burden placed upon the United States military in conducting operations against violent extremism."
According to Bloomberg, the deal is for 36 jets that will be manufactured in the United States, creating an estimated 60,000 new jobs.
The US State Department says the deal shows US efforts to help, "strengthen the security and defence architecture of the region."
It comes just days after four other Arab nations cut diplomatic ties with the Qatari government.
Bahrain, Egypt, Saudi Arabia and the United Arab Emirates all announced on last week they will withdraw their diplomatic staff from Qatar.
