India and Japan signed a logistics agreement that will allow armed forces of both sides to coordinate closely in services and supplies.
The supplies and services include food, water, transportation, airlift, petroleum, clothing, communications and medical services etc.
The agreement is known as Reciprocal Provision of Supplies and Services agreement or Acquisition and Cross-Servicing Agreement (ACSA).
It will remain in force for 10 years and will be automatically extended for periods of 10 years unless one of the parties decides to end it.
India has similar agreements with the USA, Australia, France, Oman and Singapore.
It is aimed at greater maritime cooperation and can upgrade India-Japan naval exercises as both countries are expected to share maritime facilities for mutual benefit.
