He also expressed hope of finding a solution to the diplomatic row that erupted between India and the US after the arrest of Deputy Consul General Devyani Khobragade in New York on charges of making false declarations in a visa application for her maid.
"As far as security is concerned, the matter is dealt with agencies entirely on the merits of security requirement. Security is not based on reciprocity.... It is based on threat perception," Khurshid said on the sidelines of an event.
He went on to add, "Security issues are all to be dealt by security agencies. There is no question of any compromise on security. We have been very careful right through.Reciprocity and matters like convenience, courtesies etc are another matter."
Allaying US' concerns about security of their institutions after barricades outside the embassy were removed as a fallout of the diplomatic row, as many as 150 policepersonnel have been deployed during a 24-hour period in shifts at the US embassy, school and American Centre in New Delhi.
Apart from that, two police vehicles have been permanently stationed along various roads near the embassy including Nyaya Marg.
Asked whether the US State Department clearance will come this month in the Devyani Khobragade case after the diplomat was transferred to India's permanent mission to the UN to give her full immunity, Khurshid said, "I have never been in state department so would not know how quickly it works. If you asked about MEA, I would tell you."
Khurshid said every incident must not be seen as a qualifying matter relating to the relationship with the US.
