SINGAPORE - A recent Facebook post by Prime Minister Lee Hsien Loong that touched on Vietnam's invasion of Cambodia in 1978 has sparked anger in both countries.
Last Friday (May 31), Mr Lee wrote on his Facebook that he has written to Thailand's Prime Minister Prayut Chan-o-cha to express his condolences on the death of former Thai premier and Privy Council president General Prem Tinsulanonda on May 26.
In praising Gen Prem's capabilities as a leader, Mr Lee said the former leader's premiership coincided with the then-five Association of Southeast Asian Nations (ASEAN) members - Thailand, Malaysia, Indonesia, the Philippines and Singapore - coming together to oppose "Vietnam's invasion of Cambodia and the Cambodian government that replaced the Khmer Rouge".
He said Thailand was on the frontline, facing Vietnamese forces across its border with Cambodia, and that Gen Prem was resolute in not accepting this fait accompli, and worked with ASEAN partners to oppose the Vietnamese occupation in international forums.
As a result, Mr Lee said this prevented the military invasion and regime change from being legitimised, as well as protected the security of other ASEAN countries.
Mr Lee also mentioned the issue during his keynote address at the Shangri-La Dialogue on Friday when he was talking about the formation of ASEAN.
Cambodia and Vietnam have objected to PM Lee's remarks.
Prem Tinsulanonda, who was Thailand's prime minister for more than eight years in the 1980s, died of heart failure on May 26 at age 98.
Cambodian Defence Minister General Tea Banh told the local media earlier this week that Mr Lee's comments were "unacceptable" and "not true".
He said he had brought up the matter with his Singaporean counterpart, Dr Ng Eng Hen, and requested Mr Ng to inform Mr Lee to rectify the statement.
"He (Mr Lee) did not say the truth and his statement does not reflect history. It is not true because he said Vietnamese troops invaded Cambodia," Khmer Times quoted him as saying. "We wish for him to make corrections. It is not true."
Vietnam's Ministry of Foreign Affairs said it "regretted" that Mr Lee's remarks did not "objectively reflect the historical truth" and as a result, caused "negative impacts" on public opinions.
The ministry spokeswoman Le Thi Thu Hang said the ministry has discussed this issue with its Singapore counterpart.
She added the contributions and sacrifices of Vietnam in the joint efforts with Cambodian people to end the Khmer Rouge genocide regime have been widely recognised.
PM Lee's post on Gen Prem attracted some 26,000 comments, with many that appeared to be from Vietnamese users expressing their unhappiness over his comment on the Vietnam-Cambodia issue.
One of them named Nguyen Duy Hung wrote: "With respect to you and Singapore, please correct the word "invasion". We, Vietnamese had lost a lot of blood there to help Cambodian friends from Khmer Rouge..."
In contrast, there were posts of support from users with Cambodian names, such as one Sophanna Nun, who wrote: "Thanks for telling the truth even it hurts a lot of people. You are great leader."
In a 2011 speech, former deputy prime minister Wong Kan Seng had described the Cambodian issue as one of Singapore's early tests as a country.
Giving the Fourth S. Rajaratnam Lecture organised by the Ministry of Foreign Affairs Diplomatic Academy, he said: "The invasion of a smaller country by a larger neighbour, the deposition of a legitimate government by external force and the imposition of a proxy by a foreign power became a direct challenge to the fundamentals of our foreign policy."
Mr Wong said Singapore had to respond to the invasion or it "would have undermined our credibility and posed serious implications for our own security".
"We had no sympathies for the Khmer Rouge regime. It was an issue of principle," he added.
