() will invest $1.6 billion to upgrade its factory in the city of Chengdu in western , the latest sign of how the chipmaker is deepening ties in a market that is proving increasingly troublesome for some U.S. technology peers.

As part of the upgrade, Intel said in a statement on Thursday it would bring its most advanced chip-testing technology to . In exchange it will receive local and regional government support for . 

"Deploying our newest advanced testing technology in China shows our commitment to innovating jointly with China," Intel executive vice president William Holt said in the statement. "The fully upgraded Chengdu plant will help the Chinese semiconductor industry and boost regional economic growth."

The announcement comes three months after Intel purchased a minority stake in a government-controlled semiconductor company to jointly design and distribute mobile chips, an industry that China considers to be of strategic importance. 

Intel's fortunes in China contrast with the travails of its rival,  (), which is expected to announce in the coming days a potentially record-breaking settlement with Chinese antitrust regulators. 

China's investigation into San Diego-based Qualcomm, as well as a spate of recent probes against firms including , have prompted an outcry from foreign business lobbies. They say the Chinese government is increasingly adopting strong-arm tactics to yield technology-sharing or other arrangements beneficial to domestic industry.

The government, meanwhile, has defended its regulatory scrutiny as even-handed. It has pointed to a history of Qualcomm and  facing similar antitrust probes in Western countries.

Analysts say there is a broad recognition that foreign companies must do more to stay in China's good graces.

"Intel's taking the approach that's appreciated by the Chinese government," Nomura analyst Leping Huang said. "These days if you want to make money in China, you have to invest in China."
