The 300 newly-arrived medics hail from 22 top-notch Guangdong hospitals and were welcomed by Chief Executive Carrie Lam Cheng Yuet-ngor at Liantang port.

During the ceremony, Lei Haichao, deputy director of the national health commission, said that it would be "a new challenge" for mainland medics to work in different medical institutions.

The vice president of Guangdong Provincial Hospital of Traditional Chinese Medicine, Zhang Zhongde, said they can learn alongside their Hong Kong colleagues.

Lam said she was "very touched" that the medics arrived so quickly, adding that she is confident the city can prevail and reopen its border with the mainland soon.

"They are all highly-qualified medical personnel working in the highest-grade hospitals in Guangdong," Lam said.

"They are also very young so they will be a major boost to the Hospital Authority's workforce."

The second batch of medics, Lam said, will mainly work in AsiaWorld-Expo and the North Lantau Hospital Hong Kong Infection Control Centre.

The medics will travel by designated transport between hotels and their place of work every day.

On Monday, the first batch of 75 medics - 36 doctors and 39 nurses - from 14 public hospitals in Guangzhou, Shenzhen, Foshan and Zhuhai arrived in Hong Kong.

The authority's chief manager (quality and standards) Lau Ka-hin said the mainland medics will begin clinical work soon.

He added that medics assigned to isolation facilities will perform the same duties as their local counterparts.

Association of Hong Kong Nursing Staff chairman Anders Yuen Chi-man said that it will take time for the medics to adapt given the differences between the two places' health-care systems and treatment procedures.
