Foreign Minister Don Pramudwinai and his Japanese counterpart agreed Monday to cooperate with the international community to combat terrorism in the wake of deadly attacks in Paris on Friday, as well as a bombing in Bangkok in August.
"The international community should be united to resolutely condemn the terrorist acts," Fumio Kishida was quoted by Japan's Foreign Ministry as telling Mr Don when they met on the sidelines of ministerial talks for the Asia-Pacific Economic Cooperation forum starting in Manila.
The two ministers vowed to "closely cooperate" in fighting terrorism, according to the ministry said.
With Thailand home to many Japanese residents and companies, Mr Kishida called for Thailand to help ensure the safety of Japanese nationals there and protect and promote further the good investment environment for Japanese companies in the Southeast Asian country, the ministry said.
More than 60,000 Japanese people live in Thailand and about 4,500 Japanese firms operate there, according to Japanese government data.

The ministry said Mr Kishida also reiterated Japan's support for railway and other infrastructure development projects in Thailand.
Touching on tensions in the South China Sea, where territorial claims by some Southeast Asian countries and China have overlapped, Mr Kishida said ensuring stability in the sea is vital to regional peace, and Japan has called for the rule of law to be upheld at sea, the ministry said.
"Asean as a whole should send a strong message when their leaders gather for an upcoming summit," Mr Kishida also told Mr Don, who assumed his post in August and held his first talks with his Japanese colleague.
Mr Kishida was referring to the 10-member Association of Southeast Asian Nations' summit scheduled for later this week in Kuala Lumpur.
Thailand is not a claimant in territorial rows in the South China Sea, while Japan is not directly involved in the dispute, but regards the sea as a shipping lane crucial for its oil and other imports.
Mr Kishida also expressed his hope for Thailand's early restoration of democracy following a coup in 2014. Mr Don said Thailand wants to learn from Japan's experience in implementing democracy, according to the ministry.
