The industry might think the online travel land-grab is between Priceline and Expedia - but you should probably look to the east.
As the digital behemoth Alibaba continues to scare the socks of almost everyone in ecommerce, intra-Chinese rivalry is also stepping up a gear.
This week, rival multi-vertical shopping site JD (formerly known as 360Buy) was one of a string of investors which fed in $148 million into package travel brand Tuniu.
The move is seen as a wider move by JD to bolster its travel strategy amid Alibaba's ongoing ramping up of operations with the launch of the dedicated Alibaba Travel brand in October this year.
JD was joined by investment company Hony Capital in both injecting $50 million into Tuniu via share subscription agreements (Tuniu filed for an IPO in the US in April).
The balance comes from Ctrip with $15 million and Tuniu's CEO and chairman Dunde Yu and COO Alex Yan both putting in $16.5 million each.
Yan says the investment will be used to increase its penetration into lower-tier Chinese cities and boost its technology research and development.
Yu adds:
"We also expect to deepen our partnership around shared travel resources with Ctrip, one of our existing shareholders, which further increased its holdings in Tuniu through this placement."
