Chiao Jen "C.J." Wang, 86, founder and chairman of Arlington-based International Corp. of America, which helped American businesses negotiate contracts with the Chinese government, died July 26 at Johns Hopkins University Hospital in Baltimore. He had renal failure.

Dr. Wang, an Arlington County resident, was a native of China and a mechanical engineering graduate of Jiaotong University in Shanghai.

After moving to the United States in 1945, he received a master's degree in mechanical engineering from the Massachusetts Institute of Technology and a doctorate in aeronautical engineering from Johns Hopkins. He became U.S. citizen in 1953.

He was an aerospace engineer for government contractors in California before settling in the Washington area in 1966. He then worked for what is now the Defense Advanced Research Projects Agency and became director of the office of advanced engineering.

He began International Corp. of America in 1972, shortly after President Richard M. Nixon made his historic visit to Communist China.

Dr. Wang represented Fortune 500 companies, including McDonnell Douglas Aircraft, that helped China develop heavy industry and infrastructure.

"China's culture for thousands of years has been family oriented," he once told an interviewer. "I wasn't sure if the revolution had changed this. My personal experience convinced me that, no, the tradition is intact."

The company stopped conducting business with China in 1996, and Dr. Wang had mostly worked since then at managing his company's assets.

He was a member of the Cosmos Club.

His son, Samuel M.S. Wang, died in 1984.

Survivors include his wife of 59 years, Yuen-Fung Chu "Mildred" Wang of Arlington; and three sisters.
