It was not clear what specific sanctions Washington will propose. Washington and its allies have said in recent weeks that China was considering providing weapons to Russia, which Beijing denies. Before that in New Delhi on Wednesday and Thursday, the war will be discussed by foreign ministers from dozens of countries, including Russia, China and the United States. The initial outreach by Washington on sanctions has not yet led to broad agreement on any specific measures, the sources said. Washington should make China choose between access to the U.S. financial system or aiding Russia's war, Ruggiero said, citing the sanctions approach to Iran and North Korea.
