Chinese server maker Inspur Group Ltd began a campaign to lure customers from International Business Machines Corp as the government studies whether domestic banks' reliance on IBM technology threatens national security.

Jinan-based Inspur on Wednesday unveiled its "IBM to Inspur" initiative aimed at taking the US company's market share in China, said a member of Inspur's marketing department who asked not to be named, citing company policy. Inspur hired more than 80 employees from IBM's hardware arm, he said.

Cisco weighs in on new Chinese cyber security policy

The move may help Inspur capitalize on a dispute with the US after prosecutors there charged five Chinese military officers with allegedly hacking into American companies' systems. Toppling IBM in China would be a major challenge for Inspur, whose reported 36.7 billion yuan ($5.94 billion) of revenue in 2011 represented 5.5 percent of IBM's sales for that year.

"There aren't that many alternatives for high-end banking servers, so it's quite hard to find replacements," said Arthur Hsieh, an analyst at UBS AG in Taiwan.

The People's Bank of China, the Ministry of Finance and other government agencies are reviewing domestic banks' use of IBM servers and expanding a trial program to replace them with homegrown ones, four people familiar with the matter said. China Postal Savings Bank Co is using Inspur servers as part of the trial, which began in March 2013, the people said on Wednesday.

The China-US dispute may jeopardize revenue for American companies including Microsoft Corp and Apple Inc, both mentioned by the Xinhua News Agency as cooperating with the US National Security Agency.

Cisco Systems Inc has seen China sales drop off since revelations of an NSA spying program by Edward Snowden, according to Mark Natkin, managing director of Marbridge Consulting in Beijing. Snowden was granted asylum in Russia.

The Financial Times reported on Sunday that China ordered State-owned companies to cut ties with US consulting firms.
