(Reuters) - U.S. Treasury Secretary Jack Lew told his Russian counterpart on Thursday that any oil-for-goods deal Moscow might strike with Iran could run afoul of U.S. sanctions.

"Secretary Lew reiterated our serious concerns regarding reports of a possible deal between Russia and Iran involving oil-for-goods," a Treasury representative said in a statement after Lew met with Russian Finance Minister Anton Siluanov.

"He made clear that such a deal ... could trigger sanctions against any entity or individual involved in any related transactions," the representative said.

Lew also told Siluanov a deal would run counter to an agreement between Iran and six world powers, including the United States and Russia, in which Tehran promised to curb its nuclear program in return for a modest easing in Western sanctions. The sanctions were imposed to choke off Iran's oil revenues.

Reuters reported last week that Iran and Russia had made progress on a barter deal that could be worth up to $20 billion under which Moscow would provide Russian equipment and goods in exchange for Iranian oil.
