The 75-year-old billionaire was jailed for eight years on graft and abuse of power charges after he returned to Thailand two years ago following 15 years in exile, though he was pardoned by the king six months later.
Last year, he was charged with lese-majeste over comments he made to a South Korean media outlet nine years earlier, and is set to face trial in July.
According to Thai law, defendants facing trial must remain in the country unless granted special permission by a court.
Today, a court decided to allow him to leave, citing “the benefits of international relations” as a reason for his temporary departure, though it did not elaborate on the purpose of the trip.
In December, Malaysian Prime Minister Anwar Ibrahim appointed Thaksin as his Asean adviser as he took the chair of Southeast Asia’s regional bloc this year.
Although Thaksin had previously said he would not be involved in politics, he remains active, including by campaigning for his former party Pheu Thai.
“The court has considered and allowed the defendant to leave the kingdom between Jul 2 and Jul 3, which does not affect the trial,” the court statement said.
The billionaire ex-PM must report to authorities within three days of his return.
Thailand has some of the world’s strictest lese-majeste laws, with any criticism of King Maha Vaijralongkorn or his immediate family punishable by up to 15 years in prison.
Critics and rights groups say the law is abused to stifle legitimate debate.
