Chinese e-commerce giant Alibaba has called off discussions with potential investors for a $1 billion pre-IPO round for its Southeast Asia e-commerce arm Lazada, Bloomberg reported on Wednesday, citing people with knowledge of the matter. The report says disagreement over the valuation of the Singapore-based company is the main reason behind the pre-IPO plans being suspended. Alibaba has reportedly decided not to push the round further because it believes it has sufficient funds and feels that a volatile global market means the timing is far from ideal. Nevertheless, it seems the intention to spin off Lazada remains, which means Alibaba will likely revive the plan if conditions allow in the future, according to Bloomberg sources. [Bloomberg]
