Obama, questioned in Africa on the latest twists of the international spy drama involving Snowden and his exposure of US phone and Internet surveillance programmes, did however admit he was worried about what other secrets might leak.
His comments came as Snowden remained in Russia, where he fled from Hong Kong, stuck in the transit zone of a Moscow airport, apparently unable to travel on to possible asylum in Ecuador after Washington cancelled his passport.
But he ruled out military action should Snowden eventually manage to get on a flight out of Russia.
"No, I am not going to be scrambling jets to get a 29-year-old hacker," Obama said, at a media conference in Senegal.
The US leader also said that he had not called the Chinese or Russian presidents to plead with them to hand Snowden over, because his government was using regular legal channels for an extradition case.
Obama said that the US and China relationships were broad and ranged over many issues and that he would not get down to "wheeling and dealing" with Russia and China over one extradition case.
