"On this historic occasion, the government of India extends formal recognition to the independent state of South Sudan," the Prime Minister's letter said.
The letter was handed over to General Mayardit by India's ambassador to Sudan A K Pandey, Secretary (East) in the Ministry of External Affairs Sanjay Singh told reporters.
