North Korea capital Pyongyang's official newspaper Rodong Sinmun called US President Donald Trump a "psychopath" in an editorial.
"We have a great relationship with China and I really like President Xi", Trump said as he stood beside Branstad at an Iowa community college.
For months, the Trump administration has lobbied China to exert its economic influence over the North Korean government in an effort to halt that country's nuclear weapons and missile development activities.
There are lots of reasons why the Europeans wouldn't want to go that route, not the least of which is that a secret-stealing, export-promoting, rule-of-law-despising China isn't the greatest partner for the EU.
North Korea last tested a nuclear bomb in September, but it has conducted repeated missile test since and vowed to develop a nuclear-tipped missile capable of hitting the USA mainland, putting it at the forefront of Trump's security worries.

Ohio's Republican U.S. senator says he had a secret meeting in December with North Korean officials to urge that they release a college student from his Cincinnati home area.
The State Department also said the June 21 talks covered issues such as counterterrorism and territorial rivalries in the South China Sea.
