Chinese armed police truck convoy rolls into Shenzhen as Hong Kong enters another week of protests

A convoy of armed police trucks has been stationed at a sports centre in a mainland Chinese city bordering Hong Kong, adding to speculation online that Beijing could be preparing to intervene directly in the protests roiling the special administrative region.

But a Beijing-based military expert said the movements were part of regular exercises and not cause for concern.
Footage of the trucks rolling into Shenzhen in the southern province of Guangdong began circulating online on Saturday.

On Monday, Communist Party mouthpiece People’s Daily and Global Times posted videos of the convoy in the city, saying the police were there to prepare for large-scale drills.

Dozens of the trucks as well as excavators lined a pavement next to the entrance of the Shenzhen Bay Sports Centre in Nanshan district on Monday, across the harbour from Hong Kong.

Personnel in camouflage uniforms stood at the entrances of the sports centre, but did not block access to civilians.
