Port Shelter was also mentioned in a report to the UK government in 1898 by James Stewart Lockhart, shortly after the signing of the Convention for the Extension of Hong Kong Territory. It stated the harbour is a deep water port that suitable for ships in any size. The Convention ceded Port Shelter and other areas that collectively known as the New Territories and New Kowloon, to the British Empire, as an extension of the colony of Hong Kong.
