GoogleNathan Weinberg about Sergey Brin and Larry Page visit to Google's India Research and Development Center:

The Hyderabad office, Google's new Bangalore facility, which they visited, will be devoted to research into new products to expand Google's portfolio. Seventy percent of the facility is dedicated to search, 20% to Gmail, and the rest in other areas, giving you an idea what a huge priority Gmail is to Google. The new Hyderabad office will be a support center for AdWords, and be home to engineering, human resources, online sales and services. Staying true to its famous slogan, Google's India offices will not be "evil" and operate on United States time, keeping employees at work while their families and countrymen sleep, but will run a normal India workday.

Google wants to create other such centers in Asia: China, Japan, etc.
