Parrikar is set to leave for Oman on May 18 during which he will call on the top leadership there and hold bilateral talks with his counterpart.
Oman, considered to be closest to India among the Gulf Cooperation Countries (GCC), had signed a military protocol with India in 1972, which led to a three-year deputation of Indian Navy personnel to man Oman's Navy in 1973.
An MoU on defence cooperation was also signed between India and Oman in 2005.
Parrikar will also visit UAE, which was one of the countries visited by Prime Minister Narendra Modi last year.

His visit to the country will coincide with an air exercise being held between the air force of both countries. Indian fighter planes will stop by in UAE on the way back from the Red Flag air exercise in the US.
Following Modi's visit, India and UAE had decided to establish a strategic security dialogue and boost defence ties besides resolving to work together in counter-terrorism operations, combating money laundering, drug trafficking and trans-national crimes.
The UAE also conveyed to India that it will cooperate in manufacture of defence equipment in India.

J P Nadda, also BJP's election incharge for the state, said Parivartan (change) did not just mean the change of a government but of a political culture.
"Parivartan means change of an entire political culture. Congress' political culture is based on commission whereas BJP's culture has its foundations in mission. Congress believes in reaping the fruits whereas we believe in serving selflessly," he said.
Nadda claimed that the country is taking big strides on all fronts under the Modi government and Uttarakhand has lagged behind in this forward march because of a "corrupt" and "inert" government.
"The state government is to be held responsible for Uttarakhand being left behind in this march to development. Such a government deserves to be sent back home," he said asking people to vote for BJP in the upcoming Assembly polls.
