A statement denying it killed 12 Chinese nationals on two cargo vessels travelling along the Mekong River earlier this month was issued by the United Wa State Army (UWSA).
The UWSA stated that it had nothing to do with the killings and that they occurred outside areas under its control. A section of the river north of the Golden Triangle was under the supervision of Thai authorities, the statement said.
It would only be fair of China to withhold its suspicions until a thorough investigation points without doubt to the culprit.
Deputy police chief Pol Gen Parnsiri Praphawat and a large team of investigators were sent by the Royal Thai Police Office to Chiang Rai province to investigate the killings.
A team led by Guo Shaochun, deputy director-general of its Department of Consular Affairs and head of the Center for Consular Assistance and Protection was also dispatched by China to conduct an investigation.
12 people including crewmen and family members aboard a Chinese oil tanker called the Hua Ping and a cargo boat called the Yu Xing 8 were killed by still unknown attackers.
The boats were found in Chiang Saen district of Chiang Rai on October 5 by Thai soldiers patrolling a stretch of the Mekong. The foregoing news is sourced from the Bangkok Post.
