Gavin Black: A Dragon for Christmas (USA 1979)

From the Publisher:
Paul Harris went to Peking to sell a marine engine, visit a Chinese ex-girlfriend and leave as quickly as possible. But then somebody planted a corpse in his hotel room.

"One of the best of the foreign affairs mysteries of the year... Either Mr. Black has been a visitor behind the Great Wall, or has had access to firsthand information with which he creates his artful and tensive story... The final escape scene is as potent excitement as you will find this season." - New York Herald Tribune Books
"Has fine air of authenticity, good humor.' - Saturday Review

Also available in Perennial Library is Gavin Black's You Want to Die, Johnny?
