Thailand’s King Rejects His Sister’s Candidacy for Prime Minister
Long story short, the king is being controlled by the military government :
Thailand has been under military rule since a coup in 2014 unseated forces loyal to Thaksin Shinawatra, a brash billionaire who challenged the country’s traditional power structure. The country is now led by Prime Minister Prayuth Chan-ocha, a former general and junta chief who has fashioned himself as a fierce defender of Thailand’s monarchy.
