Live updates: Trump, Biden presidential debate, analysis and reaction

Donald Trump speaks during the CNN Presidential Debate on Thursday in Atlanta.

Former President Donald Trump claimed that China, among other countries, “passed” on doing business with Iran during his presidency after he vowed that the US would not do business with any country that does so.  

“Iran was broke. Anybody that did business with Iran, including China, they couldn’t do business with the United States. They all passed,” Trump said.  

Facts First: This is a false claim.   

China’s oil imports from Iran did briefly plummet under Trump in 2019, the year his administration made a concerted effort to deter such purchases, but they never stopped – and then they rose sharply again while Trump was still president.  

“The claim is untrue because Chinese crude imports from Iran haven’t stopped at all,” Matt Smith, lead oil analyst for the Americas at Kpler, a market intelligence firm, told CNN in November.  

China’s official statistics recorded no purchases of Iranian crude in Trump’s last partial month in office, January 2021, and none in most of Biden’s first year in office. But that doesn’t mean China’s imports ceased; industry experts say it is widely known that China has used a variety of tactics to mask its continued imports from Iran.  

Smith said Iranian crude is often listed in Chinese data as being from Malaysia; ships may travel from Iran with their transponders switched off and then turn them on when they are near Malaysia, Smith said, or they may transfer the Iranian oil to other ships. 

Ali Vaez, Iran project director at the International Crisis Group, said in a November email: “China significantly reduced its imports from Iran from around 800,000 barrels per day in 2018 to 100,000 in late 2019. But by the time Trump left office, they were back to upwards to 600(000)-700,000 barrels.”  

Vaez’s comments were corroborated by Kpler data that Smith provided to CNN. Kpler found that China imported about 511,000 barrels per day of Iranian crude in December 2020, Trump’s last full month in office. The low point under Trump was March 2020, when global oil demand crashed because of Covid-19. Even then, China imported about 87,000 barrels per day, Kpler found. (Since data on Iranian oil exports is based on cargo tracking by various companies and groups, other entities may have different data.)
