"Language is not a big problem, as we have good translators. I'm also trying to learn Chinese," Wattanayagorn said, showing his determination to make the campaign a long-term effort.
"Thailand will do an evaluation of the cooperation after the campaign ends. If we feel it has been effective in fighting drug trafficking, we'll push on," he said.
Chinese officer Lan agreed and said making the campaign regular needs the backing of all four countries, as well as detailed plans and funding.
So far the campaign has resulted in 560 cases of drug trafficking being uncovered, with 812 suspects arrested, according to the Ministry of Public Security.
Police from the four countries have seized 1,931 kilograms of drugs, including heroin, opium and methamphetamine, commonly known as ice, as well as firearms.
A drug processing plant in Myanmar was also destroyed under the cooperation between Myanmar and China on May 12, which led to the arrest of three suspects and the seizure of 20 kg of ice, according to the Ministry of Public Security. Police from the two countries also confiscated a handgun, and equipment and raw materials to make drugs, it said.
"The campaign is a threat to drug traffickers," said Yu Haibin, a police officer of the department.
"Ensuring safety on the Mekong River is always in the minds of the four countries, and the campaign is a good way to do it," he said. "However, this is just the first step and we need to do a lot more in the future."
