The government has decided not to attend the London Conference on the Illegal Wildlife Trade as it is battling political problems at home.
The conference is the global stage on which the political war against the illegal ivory trade and rhino and tiger poaching is fought.
Theerapat Prayulrasidhi, deputy chief of the National Parks, Wildlife and Plant Conservation Department, said no senior officials from the government will attend this week's conference.
This is because the caretaker government is not authorised to sign any agreement which will bind the next administration, Mr Theerapat said.
Mr Theerapat said the governments in attendance will sign a declaration to prevent wildlife poaching and suppress wildlife crime which could have long-term implications for government policy.
“We will send our ambassador in the United of Kingdom to the conference. The government will reserve the right to sign the declaration.
"But don’t worry, our policy against wildlife crime is in line with the declaration," Mr Theerapat said.
The government might also need permission from the Election Commission (EC) to attend the conference. The EC is organising poll re-runs and might be too busy to consider the issue, he said.
Fifty heads of state and other senior representatives from across the world will discuss how to curb poaching.
They will focus on changes to law enforcement and the role of the criminal justice system; ways to reduce demand for illegal wildlife products; and how to support the development of sustainable alternative livelihoods to wildlife crime.
Thailand is the world’s top destination for the illegal African ivory trade. Ivory is smuggled into the country then sold to other countries in Asia.
Thailand is under considerable pressure from the global committee to stop the illegal trade.
Caretaker Prime Minister Yingluck Shinawatra last year promised Thailand will do its best to stop ivory trading in the country, but critics say little progress has been made in the meantime.
