The Department of Special Investigation (DSI) is preparing to summon Prasert Chantraruangthong to question him about the MOU with Singapore after detecting suspicious irregularities. The former ministry permanent secretary testified clearly that the political side ordered the signing.
On 20 December 2025 GMT+7, concerning the memorandum of understanding (MOU) between the Ministry of Digital Economy and Society (DE) and Prime Opportunity Fund VCC from Singapore, the DSI special investigation team questioned the former ministry permanent secretary and discovered information linking the issue to policy-level authorities. The special investigation team interviewed Wisit Wisitsora-at, the former permanent secretary of the Digital Ministry (currently serving as the chairman of the SEC), regarding the origins of the MOU signing.
Mr. Wisit stated that the MOU was directed by political authorities, with the digital ministry’s ministerial office instructing the permanent officials to proceed. Before acting, approval was obtained from the then Minister of Digital Economy. As the permanent secretary, he signed the document according to procedure. He affirmed he was unaware of details and did not personally know the signatory from the company or any company in the TIDC group. Based on this testimony, the special investigation team plans to summon political figures, including the then Minister of Digital Economy and the minister’s secretary, for further statements to uncover the facts.
This case gained attention after Chaiyachon Chidchob, the current Minister of Digital Economy, ordered the cancellation of the MOU due to discovered irregularities and multiple issues suggesting a lack of transparency that could cause damage to the government. Additionally, photographs from the signing ceremony during Prasert Chantraruangthong’s tenure as digital minister were released, showing prominent individuals witnessing the event, including Prasert Chantraruangthong, former Minister of Digital Economy; Lt. Col. Thammanat Prompao (then Minister of Agriculture); Naruemon Pinyosinwat (then Thailand’s trade representative); and Benjamin Mauerberger, also known as Ben Smith. These photos, combined with the former permanent secretary’s testimony, form critical evidence the DSI will use to expand the investigation into the political role in pushing the disputed MOU.
