At AsianInvestor's recent Women in Asset Management Forum, we sat down to interview Alexa Lam, former deputy CEO of Hong Kong's Securities and Futures Commission.

In the third part of this video interview, Lam charts the modern history of Hong Kong's economic relationship with mainland China, starting in 1978 when the city's companies started cross-border technology transfers.

Over the years Hong Kong has acted as a way of reforming the mainland's corporate culture via market listings, financial intermediary training and the internationalisation of the renminbi.

But Lam says that Hong Kong now needs a new economic model to replace this diminishing role. One option she suggests is for the city to become a financial hub for the entire One Belt, One Road region, the government-led pan-Asia initiative which Beijing has been pushing.
