BEIJING, September 19. /TASS/. China opposes a new US law that tightens sanctions against Russia and expands measures against Iran, the Global Times quoted a spokesperson for the Ministry of Commerce as saying.

According to its information, China "consistently opposes unilateral sanctions that lack authorization from the UN and a basis in international law."

"We will continue to closely follow the US side's subsequent actions and reserve the right to take all necessary measures to firmly safeguard China's national sovereignty and development interests, as well as the legitimate and lawful rights and interests of Chinese enterprises," the paper quoted the spokesperson as saying.

"We hope the US side will work with China in the same direction, maintain the stability of economic and trade relations through dialogue and consultation, and make greater contributions to upholding the world trade order and the security and stability of global industrial and supply chains."

On September 18, US President Donald Trump signed a bill introducing and expanding sanctions, duties and bans against Russia, as well as extending existing sanctions against Iran.
