Dec 1 (Reuters) - The United States, which on Monday assumed the 12-month presidency of the Group of 20 major economies, will focus on driving economic growth and prosperity, the U.S. State Department said.

"We will prioritize three core themes: unleashing economic prosperity by limiting regulatory burdens, unlocking affordable and secure energy supply chains, and pioneering new technologies and innovations," it said in a statement.
