According to Hugo Barra and Xiaomi's president, Lin Bin, Singapore is an important starting point for a lot of new businesses and that's the reason it was their first choice for the future expansion. It is expected that Xiaomi will step on the Singaporean market sometime in Q1 next year.
In fact, Taiwan was the first foreign country in which Xiaomi offered its Android smartphones. In Taiwan, it partnered with several local retail stores, where it offered its products, but customers could order directly from Xiaomi's website as well. It is highly probable that the Chinese company will use the same flexible marketing strategy in Singapore, too.
