A new urban landmark in Hong Kong.

Citibank's striking flagship branch in Hong Kong is a new landmark in Mong Kok, the busiest business district of the city. The multi-story bank is wrapped in massive exterior LED video walls that light up in a visual spectacle twice daily. The tech theme continues inside, with the branch showcasing Citi's next-generation retail-branch technologies, including interactive touch screens, video conferencing and free Wi-Fi connections for mobile customers.

The Mong Kok branch, opened this week by CEO Vikram Pandit, is the newest for Citi in Asia this year. The company now has more than 700 branches across the region, up from 100 a decade ago. The number is expected to grow to about 1,000 branches in the next three to four years.

In recent Wall Street Journal coverage (subscription required), Pandit explained the broad push in Asia as part of a strategy to position Citi for major trends driving economic growth: the rise of emerging markets and globalization. "My energies are completely focused on the Citicorp of the future, and a big part of our future is in emerging markets so that's why I'm here," he said.
