Putin also defended a cellist friend named as the alleged owner of an offshore company, describing him as a philanthropist who spent his own funds to buy rare musical instruments for Russian state collections.
Speaking at a media forum in St Petersburg, Putin said Western media pushed the claims of his involvement in offshore businesses even though his name didn't feature in any of the documents leaked from a Panamanian law firm.
The Washington-based International Consortium of Investigative Journalists said the documents it obtained indicated that Russian cellist Sergei Roldugin acted as a front man for a network of Putin loyalists, and, perhaps, the president himself.
The ICIJ said the documents show how complex offshore financial deals channeled as much as USD 2 billion to a network of people linked to the Russian president.

Putin said Roldugin, a longtime friend, did nothing wrong.
Roldugin used the money he earned as a minority shareholder of a Russian company to buy rare musical instruments abroad and hand them over to the Russian state, Putin said.
"Without publicizing himself, he also has worked to organize concerts, promote Russian culture abroad and effectively paid his own money for that," Putin added. "The more people like him we have, the better. And I'm proud to have friends like him."
Putin contended that Washington has fanned allegations of Russian official corruption in order to weaken Moscow as the US has become concerned about Russia's growing economic and military might.
Putin said it's essential to prevent the collapse of the Syrian state to stem the flow of refugees to Europe.
He praised cooperation between Moscow and Washington in efforts to broker a cease-fire, which went into effect February 27. The truce excludes the Islamic State group and the al-Qaida branch known as the Nusra Front.
