U.S. President Donald Trump made clear during open conversations at the White House with Chinese President Xi Jinping that Chinese aid to Iran is unacceptable. This was stated by U.S. Ambassador to China David Perdue to CNBC. According to the ambassador, "We made it very clear to them weeks ago that any assistance they provide to Iran – whether direct or indirect, and whether it involves intelligence, components or military equipment – is completely unacceptable. President Trump reiterated this yesterday. This is a message that repeats itself again and again."
