    Lèse-majesté proceedings linked to vaccine criticism

    Thanathorn Juangroongruangkit was charged under Thailand's lèse-majesté law after criticizing the government's vaccine policy and its reliance on AstraZeneca production through Siam Bioscience. Additional charges were reported later in 2021. The proceedings concerned speech about government policy and the monarchy-linked company rather than a proven corporate offense.

    Public-funding and vaccine-capacity controversy

    A 600 million baht government allocation to support Siam Bioscience's AstraZeneca vaccine-production capacity drew criticism from Thanathorn Juangroongruangkit over transparency and the provision of public funds to a for-profit company. The cited material reports political controversy but does not establish a finding of financial wrongdoing by the company.
