Qatar has sold $ 12 billion in global financial markets, the world's largest since the bond it sold in April of last year with a similar value.
The demand for bonds exceeded $ 50 billion despite the embargo imposed on Doha since mid-2017.
The bonds were sold in three tranches and repayment periods ranging from five to thirty years.
The bonds are higher than those sold by Saudi Arabia in January of $ 7.5 billion, with demand reaching $ 27 billion.
Reuters said the deal was the country's first test of international investors' demand after the blockade. Qatar has largely overcome the economic impact of the blockade, partly because of high energy prices, she said.
"There are many strong indicators that have made foreign investors accept Qatari bonds, including the strong financial rating for Qatar at AAA," said Al-Jazeera.net general manager Taha Abdul Ghani.
He added that Qatar's strong oil and gas production, the proven reserves of these resources and the country's large trade surplus are additional factors that strengthen the strength of the Qatari economy.
"These factors make any institution or investor welcome to invest in Qatari bonds."
Taha Abdul Ghani also said that the successful political moves of Qatar have made the siege on them narrowing to a minimum, which has positively affected the volume of demand for Qatari bonds.
Qatar's Ministry of Development Planning and Statistics said earlier that Qatar's trade surplus was 191.43 billion riyals ($ 52.6 billion).
Qatar's trade surplus surged in 2018 from 136.82 billion riyals ($ 37.6 billion) in 2017.
