Beijing. "Tragedy" - that was Alibaba Group Holding founder Jack Ma's prediction for the fate of rival JD.com in comments published earlier this year.
On Monday Alibaba signalled it is no longer writing off its smaller competitor, making a $4.6 billion investment to give it more traction in two areas JD.com does well in: logistics and electronics.
Ma's online shopping titan bought into bricks-and-mortar electronics retailer Suning Commerce Group, surprising investors given it has traditionally stayed away from physical, offline assets.
Analysts say the main draw for Alibaba is likely to be Suning's logistics network, which it says covers nine-tenths of China's counties, helping it compete with JD.com's sophisticated in-house warehousing and delivery system.
"Instead of building the network itself, it saves more time through this kind of deal," said Walter Woo, an analyst with Oriental Patron Finance Group in Hong Kong.
But even for cash-rich Alibaba the investment is a bold one, coming when its heady growth of the past few years is losing momentum.
On Wednesday, Alibaba said its revenue for the three months ended June rose 28 percent to $3.27 billion, its slowest growth rate in more than three years.
For a company long praised for its fat margins, fast revenue growth and lack of physical assets, buying a stake in Suning, which had margins last year of less than one percent, raised industry eyebrows.
Suning is now valued at 149 times earnings for the last 12 months, according to Thomson Reuters data.
In January, Ma apologized for his barbs about JD.com and its business model, saying he had spoken too openly.
JD.com's recent growth in the total value of goods sold on its platforms is likely to have given Ma more reasons for reflection.
JD.com's gross merchandise volume went from 21 percent of Tmall's, the main Alibaba site with which it competes, in the 12 months to December 2013, to 42 percent in the year ending June, according to Morgan Stanley Research.
"This likely might have triggered Alibaba and Suning to form a closer alliance to fight back," said Alicia Yap, a Hong Kong-based Barclays Internet analyst, in a Monday research note.
With China's increasingly discerning consumers drawn to JD.com's ability to use its in-house delivery system to avoid the more fragmented, chaotic one in China that its rivals depend on, Alibaba will be hoping Suning can give it a quick leg-up.
This prospect has already made JD.com investors nervous, with its shares down 12.6 percent since Monday, the biggest two-day drop since it went public in May last year, though the company is playing down the threat.
"When we began investing in same-day delivery, people wrote us off as dead," said a company spokesman in Beijing.
"More than five years later, e-commerce companies in the US and China see our superior service and realize investing is the only way they can survive."
Alibaba also wants to hook up its other Internet services with Suning, including its affiliate online payment system Alipay.
Such moves linking online to offline assets are not always welcomed by investors, as they pose the risk of slimmer margins than online-only businesses.
Earlier this month, Baidu said it would spend aggressively in this area, triggering the shares' worst two-day drop since late 2008.
Some analysts say though that if e-commerce giants want to dominate all of the retail industry, then more tie-ups like Alibaba and Suning are on the cards.
"The price they paid is indeed very high," said Orient Patron Financial's Woo.
But given how complementary the deal could be, "this may be the reason to justify this high price".
