Hong Kong's finance chief on Saturday pledged to turn the territory into a "safe haven" for international investors, and expressed confidence that the city will overtake Switzerland as the world's top cross-border wealth management hub within a few years.

In an address at a wealth management forum, Financial Secretary Paul Chan said the SAR is a sure bet for investors amid the current geopolitical situation.

"Amid growing uncertainties in the global economy, and intensifying unilateralism and protectionism, the international economic system is facing the risk of fragmentation," he said.

"Hong Kong will continue to maintain its free port status, along with a sound financial system, the free flow of capital, as well as predictable and stable government policies, to make international investors feel at ease and assured, and become a safe haven for international capital."

The minister also said Hong Kong could overtake Switzerland "within two years or at most, three" as the top cross-border wealth management centre, citing an increase in capital inflow.

Funds coming into the SAR include those from the Middle East and Southeast Asia, Chan added.
