BEIJING (Reuters) - China supports Iran holding talks on its nuclear program with the United States and opposes the use of force and "illegal" unilateral sanctions to try to resolve the issue, Chinese Foreign Minister Wang Yi told Iran's foreign minister on Wednesday.

New U.S. sanctions against Iran's energy sector point to Washington's "lack of goodwill and seriousness" over dialogue with Tehran, Iran's Foreign Ministry spokesperson said on Wednesday ahead of Iran-U.

The United States has sanctioned an Iranian liquefied petroleum gas magnate, his son and a network of companies as the Trump administration seeks to resume talks over Tehran's nuclear program.
