A large piece of aircraft debris found on the south-eastern Thai coast was being investigated, media reported Sunday.
The three-by-three-metre piece of metal, weighing around 100 kilograms, was discovered Saturday by fishermen on Nakhon Si Thammarat, around 800 kilometres south of the capital, the Bangkok Post reported.
The finding prompted speculation that the wreckage might be from Malaysia Airlines flight MH370, which went missing nearly two years ago.
Malaysia's Transport Minister Liow Tiong Lai said he instructed the country's civil aviation department to contact its Thai counterpart for further information.
He urged against speculation to avoid pain to the relatives of the 239 people aboard the Bejing-bound flight that went missing an hour after it took off from the Kuala Lumpur International Airport on March 8, 2014.
The wreck has not been found despite an extensive search of the sea bed in the southern Indian Ocean. A piece of debris that washed up on the French territory of Reunion Island last summer was confirmed to be from the ill-fated flight.
The results of Thailand's investigation into the recent debris were expected within two days, said Thanyapat Pattikongpan, a local district chief officer, according to the Bangkok Post.
