Chinese analysts warn US president’s tactics against protesters could jeopardise safety, stability and even spark constitutional crisis

One high-profile commentator also predicted that Trump’s heavy-handed tactics could escalate into a constitutional crisis.

The protests, held in response to a sweeping operation to arrest and deport unauthorised immigrants, have spread to other US cities, including San Francisco, Chicago, Houston and New York.

Shi Yinhong, an international relations professor at Beijing’s Renmin University, said the deployment of troops by Trump made his “despotic nature” much clearer to Americans and added nothing to his domestic prestige.
