Hon Hai responded to the rumor that the Vietnamese factory makes Apple MacBook: no comment.

Thanks to CTOnews.com netizen zjadc for the clue delivery! CTOnews.com, December 21, according to Taiwan's Economic Daily, the Nikkei News reported that Apple plans to move some of its MacBook products to Vietnam for the first time next year, which will be manufactured by Hon Hai as soon as May.

Hon Hai declined to comment. Hon Hai's Vietnam factory mainly supplies non-Apple products, and if it does produce MacBook in Vietnam, it will be of landmark significance to Hon Hai's manufacturing in Vietnam.

Apple has partnered with contract manufacturer Hon Hai Group to start production of the MacBook in Vietnam as soon as May next year, according to people familiar with the matter. Apple has been trying to diversify its supply chain, but it takes longer for MacBook production to shift because of the more complex supply chain needed to make laptops.

CTOnews.com learned that Apple currently produces about 20 million to 24 million MacBook a year, mainly in Chengdu and Shanghai, Sichuan.
