Defence Minister ACM Sukampol Suwannathat met his Cambodian counterpart General Tea Banh at a General Border Committee (GBC) meeting at a golf resort in Rayong province.
After the meeting, Sukampol told the press that both countries had agreed to boost cooperation in suppressing drug smuggling, illegal logging, cross-border crimes and maritime safety.
They reiterated that law enforcement would be based on basic human rights.
The meeting also endorsed a proposal to strengthen mutual trust in respect of news dissemination, emphasising the importance of constructive and correct information and news.
Thailand and Cambodia have been engaged in a series of border conflicts in recent years.
Relations appeared tense after Cambodia asked the International Court of Justice to consider a trial against Thailand over the Preah Vihear Temple.
At the press conference, Tea Banh said that border security is a sensitive issue and mutual cooperation is needed to solve the problem.
Sukampol added that both countries have to live together, and the best way for this would be to open communication channels.
