A stable and reliable economy is the key to wooing more investment, and Hong Kong's constitutional development will not deter overseas companies from investing here.

This was the message from Financial Secretary Henry Tang after opening the 30-Hour Famine function today.

Mr Tang said overseas investors are optimistic about Hong Kong, and regard the city as the world's best platform for trade and commerce.

What concerns investors most is the investment environment, he said, and a stable economy is the most crucial factor.

Political reform is only one of their considerations and will not have any impact on their investment decisions, he added.
