The government has no policy of targeting or suppressing human rights defenders, the Foreign Ministry said on Friday.
It came in response to a report issued a day prior by United Nation's Assistant Secretary-General for Human Rights Andrew Gilmour on reprisals and intimidation against people who cooperate with the international agency on rights issues.
"Thailand has no policy nor intention to reprise nor intimidate human rights defenders," said ministry spokesperson Busadee Santipitak.
The report listed Thailand, along with Asean neighbours Myanmar and the Philippines, among 38 countries that have alarming and "shameful" levels of reprisal and intimidation against human rights activists.
Acknowledging the importance of granting rights campaigners protection, the regime has introduced measures and mechanisms to help ensure their safety, the spokesperson said.
These mechanisms work to ensure they will be safe and can exercise their rights and freedom in carrying out their work, she said.
The government has set up the Working Group to Develop Measures for the Protection of Human Rights Defenders at Risk of Abuse (White List) and Prime Minister Prayut Chan-o-cha established a committee last summer to receive complaints and investigate allegations of torture and enforced disappearance, she added.
Moreover, the Witness Protection Act has been repealed and the Ministry of Justice has developed a handbook to protect rights activists. Ms Busadee said workshops have been organised to map out future measures to support them.
Moreover, official surveys are conducted regularly to find how many defenders of human rights have faced or fear abuse, with such reports being sent to the premier on a weekly basis, she said.
In Thailand's draft four-year plan for 2019-2023, rights defenders have been included as a target group, reflecting how the government recognises their role in promoting and protecting people's rights, she said.
In the report, Mr Gilmore wrote: "We are also increasingly seeing legal, political and administrative hurdles used to intimidate -- and silence -- civil society," with new laws to obstruct cooperation.
