The BBC report, with links to three related reports, is from a Beijing-based correspondent:

It is noteworthy that this incident is in Guangdong Province, the richest, most populous province and a quarter of it's exports. For a glimpse check:

Nearby are Hong Kong and Macau, which remain significant entry points and places to watch events from.

With the exception of say a city like Shanghai and the national capital Beijing, this incident couldn't happen in a worse place IMHO.
