Oman and Qatar on Monday signed agreements on military cooperation, taxation, tourism, ports, labor and investment, the state news agencies of both the Gulf states said.
Oman has been pursuing wide-ranging reforms and austerity measures since Sultan Haitham bin Tariq al-Said took power almost two years ago following the death of his predecessor who ruled for half a century.
The agreements were signed during a two-day state visit by Oman's Sultan Haitham to Qatar, one of the world's top producers of liquefied natural gas (LNG).
The deals included an agreement on double taxation and tax evasion on income and capital taxes, and an investment cooperation agreement between sovereign wealth funds the Qatar Investment Authority and the Oman Investment Authority, said Qatar's Amiri Diwan, the administrative office of Emir Sheikh Tamim bin Hamad Al Thani.
