The Royal Irrigation Department's Office 15 convened in Nakhon Si Thammarat to discuss water management strategies for the Klong Tha Di watershed using mathematical modeling, aiming to improve water administration and systematically prepare for flooding. The meeting was led by Office 15 director Suraphong Chareongarnyont and attended by Dr. Watchara Suadee, an advisor to the Irrigation Department, alongside various department officials and Dr. Pakorn Distkij, an associate professor of engineering and technology at Walailak University.

Participants agreed on guidelines for applying the mathematical model to analyze and assess water conditions in the Klong Tha Di basin by integrating data from all relevant sectors. The model will examine the hydrological characteristics of the river system, flood conditions in the area, and evaluate the effectiveness of the city's royal-initiative flood mitigation project.

Three simulation periods were established: before construction begins, during construction, and after project completion to support water management planning and flood prevention efforts. The Irrigation Department intends to apply technology and innovation in water management alongside academic expertise to improve forecasting capabilities, address climate change impacts, and ensure sustainable water resources for the public. The mathematical model is expected to be completed by October 2025 as a key tool for supporting decision-making and water management in the Klong Tha Di watershed going forward.

The Royal Irrigation Department's Chonburi Irrigation Project is closely monitoring construction of the Nam Khem Canal water-discharge gate in Chonburi Province to ensure the work meets schedule and engineering standards, while strengthening water management efficiency and security in the region.

Irrigation Department officials from the Chonburi Project and Regional Office 9 visited the construction site in Wat Bosakon Subdistrict, Panasnikum District, to oversee progress, verify compliance with project plans and construction standards, and accelerate the project's advancement for effective local water management.

Vachara Promkhunapon, director of the Chonburi Irrigation Project, stated that the progress review covered inspections of all construction elements, including the gate structure, reinforced concrete work, and drainage systems, as well as contractor performance monitoring. The team will also address any problems or obstacles that could impact the project.

The Nam Khem Canal discharge gate is a critical irrigation infrastructure project for Chonburi's water management. It will improve water control and drainage efficiency, support agricultural water supply, reduce flood damage during monsoon season, and ensure adequate water availability during the dry season. The Irrigation Department will maintain close oversight to complete the project on schedule, meet engineering standards, and enhance the region's water management capabilities for long-term benefits to residents, agriculture, and economic development.

The Commerce Ministry has joined forces with Thailand's Internal Security Operations Command (ISOC) to tackle cross-border nominee business practices and shell companies that are destabilizing the economy. Poonpong Nayanaprakan, director-general of the Trade Business Development Department, announced the partnership with Major General Natthasisth Kongchinsasthithi, head of ISOC's Coordination Centre 2, to coordinate efforts in preventing and prosecuting nominee businesses under the Foreign Business Act of 1999.

The two agencies will work together to block and remedy shell company and nominee business schemes by implementing stricter legal registration procedures, including screening for suspicious accounts, requiring Thai shareholders in joint ventures to provide three months of bank statements, and introducing digital identity verification. These measures aim to prevent the establishment of nominee-linked risk enterprises and eliminate fraudulent corporate structures. Currently, there are 1,003,706 registered businesses in Thailand, of which 119,116 are Thai-classified entities with foreign investors holding stakes between 0.01 and 49.99 percent.

Major General Natthasisth stated that ISOC's Coordination Centre 2 prioritizes security matters related to foreign nationals, including migrant labor, human trafficking, and identity fraud, which directly impact social stability and security. The partnership will integrate the Commerce Ministry's strict corporate registration mechanisms with ISOC's security operations to monitor, share intelligence, and intercept foreign nationals illegally posing as Thai business owners or evading regulations. This comprehensive coordination aims to strengthen social security, protect Thai entrepreneurs, and ensure long-term economic stability.

On July 15, 2025, special DSI investigators arrested Mallika (surname withheld), an executive and director of a prominent firm, under a criminal warrant dated July 13. She is accused of conspiracy to commit fraud, operating unlicensed securities brokerage services, conducting unauthorized futures trading, entering false computer data, and money laundering offenses. The arrest took place at a well-known hospital after Mallika claimed she was ill and required medical treatment, with plans to be discharged at 8:30 a.m. DSI officers executed the warrant and took her into custody before transferring her to the Technology and Information Crimes Division at the Government Complex for further legal proceedings. Officers continuously recorded video and audio throughout the arrest and custody transfer in compliance with Thailand's 2022 Anti-Torture Act. When Mallika arrived at DSI headquarters at 9:05 a.m., she was wearing a cream-colored long-sleeved shirt, brown trousers, a black face mask, and eyeglasses. When journalists attempted to ask if she had any statement regarding the arrests or connections to recently detained figure Coach James, Mallika declined to comment and kept her head down while being escorted upstairs for formal charges and questioning. DSI investigations revealed that four brokerage companies were involved in the scheme: one focused on training and seminars, one registered in Saint Vincent and the Grenadines, one offering technical analysis and investment education, and one registered in the United Kingdom that had been warned for operating without proper financial services licensing and operating as a scam.

On July 15, the Chinese Embassy in Bangkok released a statement about an earlier meeting between Chinese Ambassador Zhang Jianwei and Thai Democrats party leader Natthaphong Ruengpanya. Ambassador Zhang outlined the intent of Chinese Communist Party leader Xi Jinping's speech marking the party's 105th anniversary and expressed China's willingness to strengthen exchanges and learning with all Thai political parties to promote development of both nations.

The ambassador said China understands concerns about environmental systems and public health in the river basin. He stated that issues affecting cross-border waterways between Thailand and Myanmar require impartial, scientific, and responsible investigation. China is willing to deepen cooperation on water resource and ecosystem management with other basin nations and supports Thailand and Myanmar in conducting joint assessments to address the issue properly.

However, the statement objected to what China called baseless accusations and smears made by certain individuals before facts are clarified and responsibility determined. It urged the Thai Democrats to maintain an impartial and rational stance. Party leader Natthaphong congratulated the Chinese Communist Party on its 105th anniversary and expressed willingness to learn from the party's experience while promoting understanding and trust between the two countries.
