The government remains committed to large-scale developments despite challenges brought about by the geopolitical and economic situation, a top adviser for Chief Executive John Lee has said.

Stephen Wong, who heads the Chief Executive's Policy Unit, also said the city's leader hoped the administration would work more closely with the market.

"We don't underestimate the challenges... but also, on balance, we are very optimistic and we obviously have faith in the future, which is why the government is committed to large-scale developments, for example, in San Tin, a science and tech city, and the Northern Metropolis," Wong told RTHK's Your Home Address programme on Saturday.

"These are big developments that are saying that we have faith in our future. We trust that the future will bring further development to Hong Kong. So I think as long as there's a capable government that works closely with society, with the efficient market, then we can bring opportunities to a very special place."

In 2022, Wong was appointed the head of the policy unit, which serves as a think-tank for the Chief Executive in formulating policies by conducting research and gathering opinions.
