JPMorgan Chase & Co. Chief Executive Jamie Dimon said Wednesday that business leaders see signs of economic growth but are increasingly concerned about long-term government deficits.

Dimon, speaking after a meeting of the influential Business Council, said executives see "broad-based" signs of economic growth internationally and in the U.S.

Consumers are spending more, and there are fewer delinquencies, he said; manufacturing is up, and companies are hiring more aggressively than a year earlier.

But Business Council members are increasingly skittish about the long-term U.S. deficit spurred by growing entitlement spending, he said.

"The group obviously is concerned about" these deficits, Dimon said.

He declined to discuss the Greek debt crisis, which has rattled international stock and bond markets.
