LUBMIN, GERMANY - FEBRUARY 02: A map shows the course of the Nord Stream 2 gas pipeline from Russia to Germany on the exterior of an informational booth close to the receiving station for Nord Stream 2 on February 02, 2022 near Lubmin, Germany. Nord Stream 2, which is owned by Russian energy company Gazprom, is to transport Russian natural gas from Russia to Germany along over 1,200km of twin pipeline stretching across the bottom of the Baltic Sea. While Nord Stream 2 was completed in September of 2021, operation has been held up by German regulators. Most recently both German and EU officials have raised the possibility of halting Nord Stream 2 due to the build-up of Russian military forces on the border to Ukraine. The build-up has stoked international fears of an imminent military invasion. (Photo by Sean Gallup/Getty Images)

WASHINGTON (AP) — The U.S. and its allies are working on new measures to cap the price of Russia’s oil, its main source of revenues. Leaders of the Group of Seven industrial nations have tentatively agreed to back a cap to force Russia to accept below-market prices for oil. The goal is to help bring Russia’s war on Ukraine to a halt while possibly lowering energy costs. Treasury Secretary Janet Yellen is touring Indo-Pacific countries to lobby for the price cap proposal. In Japan on Tuesday, U.S. and Japanese officials agreed to explore the feasibility of price caps. Russia hasn’t signaled a response. The Kremlin could retaliate by taking its oil off the market, which would cause more turmoil.
