SINGAPORE - The Chinese mainland remained Singapore's largest source of visitors this year, with arrivals reaching 2.93 million in the first 11 months, according to data released on Monday by the Singapore Tourism Board.

In November, arrivals from the Chinese mainland rose 16.5 percent year-on-year to 203,530. Local media attributed the increase to China's rollout of an autumn school holiday, piloted in cities across provinces including Zhejiang, Sichuan and Guangdong. The additional three days off, when combined with weekends, extended breaks to five days.
