Blue Diamond Affair
The Blue Diamond Affair is a series of unresolved crimes and embittered diplomatic relations triggered by the 1989 theft of gems belonging to the House of Saud by a Thai employee. The affair has soured relations between Saudi Arabia and Thailand for nearly 30 years.
In 1989, Kriangkrai Techamong, a Thai worker, stole jewellery and other valuable gems from the palace of Prince Faisal bin Fahd, where he was employed as a servant. Kriangkrai had access to the prince's bedroom and hid the stolen jewellery in a vacuum cleaner bag at the palace. It included a valuable blue diamond and other gems, which Kriangkrai then shipped to his home in Lampang Province, Thailand.
A Royal Thai Police investigation by a team headed by Lieutenant-General Chalor Kerdthes led to Kriangkrai's arrest and the recovery of most of the stolen jewellery. Kriangkai was sentenced to seven years in prison, but he was released after three years as he cooperated with the police and had confessed.
Lieutenant-General Chalor's team flew to Saudi Arabia to return the stolen items. However, the Saudi Arabian authorities discovered that the blue diamond was missing and that about half of the gems returned were fake.
In Bangkok, rumors spread in the local press that charity gala photos captured a number of government wives wearing diamond necklaces resembling those stolen from the palace. This fueled Saudi suspicions that Thai police and VIPs had taken the jewels for themselves.
Mohammad al-Ruwaili, a Saudi Arabian businessman close to the Saudi royal family, traveled to Bangkok to investigate on his own. He went missing on 12 February 1990 and is presumed to have been murdered. Prior to his disappearance, on 4 January 1989, a Saudi diplomat was murdered in Si Lom, Bang Rak District, Bangkok. On 1 February 1990, three more Saudi diplomats were murdered in Thung Mahamek in Bangkok's Yan Nawa District. The murders remain unsolved, and no connection to the jewelry theft has been established, despite the Saudi government's view "...that the Thai government had not done enough to resolve the mystery surrounding Al-Ruwaili's assassination and that of three other Saudi diplomats."
Lieutenant-General Chalor was later charged and convicted of ordering the 1995 murder of the wife and son of a gem dealer allegedly involved in the affair, and he was sentenced to death. The Thai Supreme Court upheld the judgement and sentenced Chalor to death on 16 October 2009. However, Chalor's sentence was reduced to fifty years imprisonment by King Bhumibol Adulyadej on the King's 84th birthday. Six other policemen were also convicted of involvement in the murders. One of those involved, Police Lieutenant-Colonel Pansak Mongkolsilp, was sentenced in 2002 to life in prison. The term was upheld on appeal in 2005, but he was released in 2012.
Diplomatic and economic repercussions
Relations between the two countries worsened further following the murders. Saudi Arabia stopped issuing work visas for Thais and discouraged its own citizens from visiting Bangkok. Diplomatic missions were downgraded to the chargé d'affaires level. The number of Thais working in Saudi Arabia fell from 150,000-200,000 in 1989 to just 10,000 in 2008. The cost to Thailand was about 200 billion baht in remittances, as fewer Thai workers were permitted to work in Saudi Arabia.
On 17 March 2016 Kriangkrai Techamong, then 65, told reporters at his home in Lampang that he would become a monk for the remainder of his life to repent for his dishonest actions. He had spent nearly five years in Thai prisons for his theft. Kriangkrai said he believes the missing Blue Diamond is cursed and said its theft had brought a series of calamities on himself and his family.
Chalor Kerdthes was granted a royal pardon and was released in August 2015. He was present at Kriangkrai's ordination ceremony.
On 22 March 2019, Thailand's supreme court acquitted five police officers over the abduction and murder of Saudi businessman Mohammad al-Ruwaili in 1990. The court cited lack of evidence. Over the years, charges against the five policemen were repeatedly thrown out. A criminal court dismissed the case in 2014, a ruling upheld by an appeals court the following year.
