WASHINGTON — When President Trump calls old friends on one of his iPhones to gossip, gripe or solicit their latest take on how he is doing, American intelligence reports indicate that Chinese spies are often listening — and putting to use invaluable insights into how to best work the president and affect administration policy, current and former American officials said.
Mr. Trump’s aides have repeatedly warned him that his cellphone calls are not secure, and they have told him that Russian spies are routinely eavesdropping on the calls, as well. But aides say the voluble president, who has been pressured into using his secure White House landline more often these days, has still refused to give up his iPhones. White House officials say they can only hope he refrains from discussing classified information when he is on them.
Mr. Trump’s use of his iPhones was detailed by several current and former officials, who spoke on the condition of anonymity so they could discuss classified intelligence and sensitive security arrangements. The officials said they were doing so not to undermine Mr. Trump, but out of frustration with what they considered the president’s casual approach to electronic security.
American spy agencies, the officials said, had learned that China and Russia were eavesdropping on the president’s cellphone calls from human sources inside foreign governments and intercepting communications between foreign officials.
The officials said they have also determined that China is seeking to use what it is learning from the calls — how Mr. Trump thinks, what arguments tend to sway him and to whom he is inclined to listen — to keep a trade war with the United States from escalating further. In what amounts to a marriage of lobbying and espionage, the Chinese have pieced together a list of the people with whom Mr. Trump regularly speaks in hopes of using them to influence the president, the officials said.
Among those on the list are Stephen A. Schwarzman, the Blackstone Group chief executive who has endowed a master’s program at Tsinghua University in Beijing, and Steve Wynn, the former Las Vegas casino magnate who used to own a lucrative property in Macau.
The Chinese have identified friends of both men and others among the president’s regulars, and are now relying on Chinese businessmen and others with ties to Beijing to feed arguments to the friends of the Trump friends. The strategy is that those people will pass on what they are hearing, and that Beijing’s views will eventually be delivered to the president by trusted voices, the officials said. They added that the Trump friends were most likely unaware of any Chinese effort.
