Indonesia has reportedly suspended military cooperation with Australia over the use of training materials that the Southeast Asian nation allegedly found 'insulting'.
In a statement, Australia Defence Minister Marise Payne said: "Late last year concerns were raised by an Indonesian TNI (Indonesian National Armed Forces) officer about some teaching materials and remarks at an Army language training facility in Australia.
"The Australian Army has looked into the serious concerns that were raised and the investigation into the incident is being finalised.
"Indonesia has informed Australia that defence cooperation would be suspended. As a result, some interaction between the two Defence organisations has been postponed until the matter is resolved. Cooperation in other areas is continuing."
The teaching materials were found at a military base in Western Australia where Indonesian soldiers were being trained in counter-terrorism and border protection, according to Reuters.
The material has been removed and will be replaced with appropriate material in due course. Currently, training is not occurring as 'a relatively small number' of Indonesians have been withdrawn from Australia.
The navies of both the countries are expected to participate in multinational training exercises next month.
Payne added: "Australia is committed to building a strong Defence relationship with Indonesia, including through cooperation in training. We will work with Indonesia to restore full cooperation as soon as possible."
