Between July 26 and August 3, torrential rains and flooding devastated the region. Chieng So commune reported four casualties and missing persons, with 262 homes affected—13 of which were completely destroyed. Huoi Mot commune saw 184 households impacted, including 44 homes that collapsed or were swept away. Landslides seriously disrupted transportation infrastructure, leaving many hamlets isolated.
Local authorities have been working closely with relevant agencies to provide relief, address damage, and restore stability for affected residents.
While inspecting the flood-hit areas and witnessing residents’ living conditions, Deputy Prime Minister Long expressed deep sympathy for the losses suffered and encouraged communities to remain resilient.
He urged Son La province to prioritize support for affected families, help restore livelihoods, and promote recovery in both daily life and production.
During his visit, the Deputy Prime Minister delivered 96 gift packages to households in Chieng So and Huoi Mot communes.
The Military Region 2 Command also donated two tonnes of dry food to flood-affected families. Additionally, the Son La Provincial Party Committee, People's Committee, and Viet Nam Fatherland Front Committee provided essential supplies and gifts to households in the two communes.

In a related effort, Deputy Prime Minister Ho Duc Phoc signed Decision No. 1653/QD-TTg on August 2, 2025, allocating VND 250 billion in emergency funds from the State budget to assist Son La, Dien Bien, and Nghe An provinces.
Dien Bien and Nghe An each received 100 billion VND, while Son La was granted 50 billion VND to support immediate recovery and stabilisation of life after the disaster.
Further support came from the capital city of Ha Noi, which pledged 8 billion VND to aid Dien Bien and Son La provinces. Of this, 5 billion VND was allocated to Dien Bien and 3 billion VND to Son La, aimed at helping affected residents rebuild and resume production. Secretary of the Ha Noi Municipal Party Committee, Bui Thi Minh Hoai, also sent letters of sympathy to the hardest-hit areas.
