The four critical care specialists will discuss with clinical medical experts in Hong Kong on the treatment of severe and critical COVID-19 cases, and share the treatment experience of COVID-19 patients in the mainland.

Also on Saturday, the construction of two community isolation and treatment facilities built with assistance from the mainland began at Penny's Bay and Kai Tak Pier in Hong Kong, respectively.

Designed and constructed by China State Construction International Holdings Ltd, the two isolation facilities are expected to provide about 9,500 quarantine units when fully operational.

On behalf of the Hong Kong residents, HKSAR Chief Executive Carrie Lam expressed her heartfelt thanks to the central leadership for their great attention, care and full support to Hong Kong at the commencement ceremony held at Penny's Bay quarantine site.

The HKSAR government would like to express its sincere gratitude to the China State Construction International for its professionalism and sense of responsibility in assisting Hong Kong in the fight against COVID-19, Lam said.
