Even as he seeks Beijing’s help on North Korea, President Donald Trump asked his trade office on Monday to consider investigating China for the alleged theft of American technology and intellectual property.

Trump, in the midst of a 17-day vacation, left his New Jersey golf club to return to the White House to sign an executive action on the probe. He suggested that more steps would be taken against China on trade issues.

“This is just the beginning – I want to tell you that,” Trump said. “This is just the beginning.”

There is no deadline for deciding if any investigation is necessary. Such an investigation easily could last a year.
