WASHINGTON, Sept 23 (Reuters) – US Democratic Senator Jeanne Shaheen said on Wednesday President Donald Trump should press Chinese President ‌Xi Jinping at a summit this week over China’s ‌support for Iran, saying that Chinese firms were helping Tehran economically and militarily.

• ​In a Senate speech, Shaheen cited reports that Iran obtained high-resolution satellite imagery of a base in Jordan from Chinese entities before launching a missile attack that killed three American soldiers and wounded ‌four others.

• She noted ⁠that about 90% of Iran’s oil exports go to China and provided it with “billions of dollars ⁠of revenue” and a “critical economic lifeline.”

• Shaheen said Chinese and Hong Kong companies had also supplied components used in Iranian ballistic missiles ​and drones

• ​She urged Trump to “use his ​leverage” with Xi to stop ‌Chinese firms from providing satellite imagery, missile and drone parts and access to markets for sanctioned Iranian oil.

• “If we want to bring this war to an end, we need to cut off the outside support that allows Iran to keep fighting, and ‌that starts with China,” she said.

• ​Shaheen said the administration should enforce ​sanctions against Chinese entities ​helping Iran, “and if China doesn’t stop, Congress should ‌impose additional consequences.”

• She said Trump ​should also consider ​using authorities in recently enacted Russian sanctions legislation against Chinese purchasers of Russian energy, arguing that China was “the top ​funder of the ‌war in Ukraine, as well as being one of the ​top funders of the war in Iran.”
