Tmall and Taobao, the B2C and C2C arms of e-commerce giant Alibaba Group, reached 1 trillion yuan ($160 billion) in combined sales by the end of November.

China's explosive e-commerce landscape has changed buying habits in the country. Around 30 percent of transactions were made in the apparel sector, with total sales hitting 300 billion yuan ($48.27 billion). According to the National Bureau of Statistics, nearly 36 percent of purchases of shoes, clothes and bags were completed via Tmall or Taobao.
