MANILA, Philippines — A Chinese and a Chinese-American, both associated with the medical device industry, have been kidnapped for ransom and killed.

The victims arrived in the Philippines on June 20 on a business trip, but they were kidnapped by unidentified persons.

One of the victims is Xia Ke Fu, 39, a marketing director at Suzhou RainMed Medical Technology and an alumnus of Hunan City University.

The identity of the other victim, a Chinese-American, is being withheld by the authorities at the request of his family. The US Federal Bureau of Investigation is reportedly assisting in the probe.

The kidnappers killed the victims on June 24 despite their families paying a ransom of three million RMB. Their remains were recovered in a province in Luzon.

The Chinese embassy has expressed concern to Malacañang about crimes targeting Chinese nationals.

Chinese Ambassador Huang Xilian met with Executive Secretary Lucas Bersamin last Monday at the Palace.
