"We are looking at a future for a possible joint lunar mission. In future, we will also be looking at how we can make use of this relationship for generating more input for climate change studies," Mr Kumar told reporters at the Asia Pacific Regional Space Agency Forum 24 conference in Bengaluru.
Mr Kumar said there is a visible change in the relationship between space agencies of India and Japan, which are both working together for looking at possible future cooperative mission.
Asked if China took into account the "competitiveness" of the Indian Space Research Organisation or the ISRO to announce their plans to cut the cost of launching satellites, Mr Kumar said there is a move by space agencies around the world including India and China, to reduce the cost of accessing space.
"Hence, in this context, almost all agencies are working towards making the cost of access to space cheaper and cheaper," he said.
Recently, China had joined the global race to cut the cost of launching rockets, and announced its plans to bring down prices to $5,000/kg.
