Chinese and Vietnamese police have arrested a man suspected of killing a Vietnamese woman during her business trip to China in September, a source told Thanh Nien.
The man was arrested in Taiwan, the source said.
He reportedly told police that he was hired to kill Ha Thuy Linh, 45, director of Ha Linh Ltd. Co., a tea company based in Vietnam's Central Highlands province of Lam Dong.
The man then fled to Taiwan after the crime, according to the source, who added that Linh was killed due to business conflicts.
Police are still investigating the mastermind behind the murder.
Linh reportedly came to China on September 19. Three days later, the Chinese consulate in Ho Chi Minh City informed her company of her death.
According to the source, Linh came to China to sign a contract to sell oolong tea. She was attacked and poisoned by a stranger at the airport.
She thought the injuries were not serious and did not go to hospital.
She came to a hotel and then reported the attack to Chinese police. Later in the evening, she died.
Linh established her company in 2008. The company is known as one of the largest oolong tea exporter in Lam Dong.
Her body has not been repatriated as the investigation continues.
