CNN reports that on Friday, President Donald Trump canceled Secretary of State Mike Pompeo's trip to North Korea, citing the lack of progress on denuclearization and blaming China. "Because of our much tougher Trading stance with China, I do not believe they are helping with the process of denuclearization," Trump tweeted. Trump is right. His trade war with China is undermining diplomatic efforts to denuclearize North Korea, as well as other US objectives. Trump promised Americans that a trade war would be "good and easy to win." While the trade war may be hurting China more than the US, tariffs are also taking a toll on American soybean farmers and businesses that rely on Chinese imports. Experts expect American consumers to be hit hard if the reciprocal tariffs keep escalating.Trump still seems to think that this trade war is going to lead to an easy win. Earlier this week, Trump boasted at a rally: "When I came we were heading in a certain direction that was going to allow China to be bigger than us in a very short period of time. That's not going to happen anymore." Trump's attitude is being interpreted in Beijing as a sign that Trump doesn't just want to equalize a trade imbalance, but instead wants to stop China's growth altogether. That has rankled Beijing, with some likening it to the start of a new Cold War...So it's no surprise that we're seeing the diplomatic consequences of our deteriorating relationship with China. The cancellation of Pompeo's visit to North Korea shows that Trump may be beginning to grasp just how significant a problem this could be for US national security.

The Wall Street Journal reported that Chinese ride-hailing giant Didi Chuxing Technology Co. said it is temporarily halting one of its services for the second time in three months after police said a Didi driver raped and murdered a female passenger in eastern China. Didi, which said it plans to halt its Hitch carpool service as of Monday, is also firing two executives in charge of the carpool business and customer service, the company said on Sunday.One of the world's biggest tech startups, Didi dominates the ride-hailing market in many cities in China and is Uber Technologies Inc.'s chief rival globally. It was the second death since May involving a passenger using Didi Hitch, a service that allows private car owners to register as drivers. The latest incident triggered widespread criticism of Didi on social media, and state news agency Xinhua blasted Didi in a commentary Sunday for "indifference" to the safety of passengers.
