The China Daily advertising insert that President Trump complained about was published on Sunday. It ran in the Des Moines Register, the largest newspaper in the farm state of Iowa. CGTN's Wang Guan spoke with former US Under Secretary of State Robert Hormat. He shared his thoughts on Trump's accusation against China.

ROBERT HORMATS FMR US UNDER SECRETARY OF STATE, 2009-2013 "I'm very puzzled by why he would say that, because the advertisement is very clearly designated as having been developed and paid for by the China Daily, which is clearly labeled as an organ of PRC. So there's nothing disguised about it. It's quite clear who developed it, who paid for it, and who put it in the paper. It's information that China supplying to people who read the paper, and it's not designed to be covert or using any kind of digital technology. It's very very clearly open in the press. And other people express their views in the American press, that's one of the benefits of the First Amendment. Countries have done this for years, taking out ads to convey information that they would like to convey. People can read it, they can agree with it, or disagree with it. It's up to them."
