Alibaba Group’s co-founder Jack Ma on Monday sought to allay concerns about Malaysia’s ongoing review of Beijing-backed investment deals, but at the same time he urged Prime Minister Mahathir Mohamad’s one-month-old government to keep the country’s doors open to Chinese investors. His two-day visit to Malaysia also saw him open Alibaba Group’s new office near Kuala Lumpur at the UOA corporate building in Bangsar South – its first country office in Southeast Asia. Ma said Mahatir’s brain child “ Multimedia Super Corridor” inspired him to co-found Alibaba Group. Since taking office, the Prime Minister has set in motion sweeping economic reforms that include a review of Chinese-backed infrastructure deals approved by Najib. Some of the deals are deemed by Mahathir to be too expensive and not beneficial to Malaysian interests.
