Polish Defence Minister Władysław Kosiniak-Kamysz said the memorandum of understanding could be ready for signing within weeks.
He spoke at a news conference in Warsaw after talks with his visiting Latvian counterpart Andris Sprūds.
Kosiniak-Kamysz said Poland and Latvia share a common history, including past oppression by Russia, and now face the shared task of ensuring long-term security.
"Our main responsibility today is to ensure a secure future," he said.
Sprūds said bilateral cooperation with Poland is of strategic importance to regional security.
He noted that the two countries jointly support initiatives such as the Eastern Shield and the Baltic Defence Line.
Both ministers confirmed that their countries have withdrawn from the Ottawa Convention, which bans anti-personnel land mines.
“The entire eastern flank has pulled out of the Ottawa Convention, not to attack anyone, but to defend our own territory,” Kosiniak-Kamysz said.
He declared that Poland remains a "loyal ally" and "will fulfill all its commitments" to Latvia, including NATO’s Article 5 guarantee of collective defence.
Kosiniak-Kamysz said the new agreement would allow for closer cooperation and would be signed in Riga, Polish state news agency PAP reported.
The two ministers also highlighted the role of the NATO multinational battlegroup stationed in Ādaži, Latvia, which is led by Canada and includes a Polish tank company.
Kosiniak-Kamysz said the planned agreement would expand the capacity of the Polish contingent.
Sprūds described Poland as a "highly respected and valued ally," adding that Polish troops in Latvia are "treated like family."
The two sides said they were also discussing ways to expand cooperation in defence industry projects, as well as in drone development. Poland is part of a drone coalition supporting Ukraine that is led by Latvia.
The NATO battlegroup in Latvia has been stationed there since 2017 as part of the alliance’s Enhanced Forward Presence (eFP).
It includes troops from 14 countries and is expected to reach full combat readiness this year, with more than 3,500 allied soldiers.
In addition to Poland and Canada, the battlegroup includes troops from Italy, Albania, Slovenia, Spain, Denmark and, as of this year, Sweden, according to the PAP news agency.
