HONG KONG: China’s aviation regulator on Friday demanded Cathay Pacific Airways suspend personnel who have engaged in illegal protests in Hong Kong from staffing flights into its airspace from August 10.

Hong Kong has been embroiled in increasingly violent anti-government street protests for the past two months, which a top Chinese official described this week as the greatest crisis since its return from British to Chinese rule in 1997.

Last week, a Cathay pilot was among over 40 people charged with rioting for allegedly taking part in violent clashes with the police near Beijing’s main representative office in the city.

On Friday night, the Civil Aviation Administration of China said that Cathay crew who have engaged in the protests pose a threat to aviation safety in mainland China, according to a statement on its website.

The aviation authority ordered Cathay to provide identification information for its crew on mainland-bound flights.

Crew members that have not gained the authority’s approval will not be allowed into its airspace, including on flights bound for other destinations.

The airline has also been ordered to draw up proposals to strengthen safety and security, said the statement.

In response, a Cathay Pacific spokesperson said: “We have received the directive and are studying it very carefully. We are treating it seriously and are following up accordingly.”

“The safety of our passengers is always the top priority of Cathay Pacific. There is zero tolerance for any inappropriate and unprofessional behaviour that may affect aviation safety. We deal with these incidents very seriously.”

Cathay said in a statement on Thursday it respects “everyone’s right to express themselves in a peaceful and respectful manner,” while insisting it “recognises that Hong Kong SAR is a part of China.”

“We do not condone any activities that jeopardise the stability of Hong Kong, or any actions that may affect aviation safety,” said the company.

Hong Kong’s chief executive Carrie Lam on Friday urged an end to the violence, claiming that the protests are dragging on the city’s economy.

Hong Kong-listed Cathay is 45% owned by Swire Pacific and 22.7% held by Air China , according to Refinitiv Eikon.
