By Gerry Shih BEIJING (Reuters) – IBM will help Chinas largest server vendor Inspur International design server systems, the two companies said on Friday, an unexpected development in what has been a politically charged rivalry in the Chinese technology market. Since last year Inspur has aggressively marketed its servers to Chinese state-owned firms as a replacement for IBM (International Business Machines Corp) systems while U.S.-China relations have worsened dramatically over mutual suspicions of cyber-spying. Inspur shares soared in late May after it told Chinese news outlets that its servers had begun to replace the U.S. The Chinese firm has coined the term I2I – IBM to Inspur – as a marketing catchphrase.
