Hong Kong-based airline Cathay Pacific and its largest shareholder Swire Pacific said they condemn all violent acts that undermine the "one country, two systems" principle and strongly support the government of China's Hong Kong Special Administrative Region (HKSAR).

The two companies issued statements respectively on Tuesday. Cathay Pacific said it is deeply concerned by the ongoing violence and disruption impacting Hong Kong, and resolutely supports the SAR government, the chief executive and the police in their efforts to restore law and order.

Cathay Pacific also condemned all illegal activities and violent behavior, which seriously undermine the fundamental principle of "one country, two systems" as enshrined in the Basic Law.

The airline said its present focus is to ensure safe and secure operations for the customers and staff.

"We abide by the rules and regulations of the Civil Aviation Department of the SAR government and those of all the countries We serve and over whose airspace we fly. We will comply with the safety directives of the Civil Aviation Administration of China (CAAC) at all times," it said.

Swire Pacific said that rule of law is the cornerstone of Hong Kong's flourishing economy and people's peaceful life, so "We must act now to stop the violence and preserve stability, peace and prosperity of Hong Kong."

Swire Pacific fully supports Cathay Pacific's strict implementation of all CAAC's directives to ensure safety and its zero tolerance approach to illegal activities.
