Chinese visitors are the fastest-growing­ segment of US tourism — shopping for designer purses, taking pictures at historical monuments, touring college campuses in record­ numbers every year — and Massachusetts tour operators, hotels, and attractions are rolling out the red carpet for this lucrative tourist group.

The Charles Hotel in Cambridge just launched a website hosted in Hong Kong to reach Chinese visitors. Wrentham Village Premium Outlets is decorating its information center in red and gold crepe to mark the Chinese New Year next month. Trademark Tours has expanded its partnership with Harvard University — one of the most popular destinations for Chinese tourists — to create more workshops aimed at Chinese travelers, including topics such as “How to Find Happiness in America.”
