This is a snippet of footage edited by the HK media and released by the HK media to capture your attention with an anti-China headline that they likely intended to achieve all along when setting up the interview.
The WHO official almost certainly ended the call because the journalist couldn’t honour prior interview conditions. He gave her a warning, she persisted with her hunt for an off-topic, anti-China headline. The WHO official probably ended the call because he correctly identified what was happening.
Beyond mere media bias, the sheer bigotry and hatred is shocking. I’ve seen several supposedly well-adjusted HK university students launch animalistic racial tirades on social media about China.
All Chinese or Hong Kong reporting about the other should be viewed through the lens of a dangerous, ongoing Hong Kong / China identity war.
