Japan will set up a new joint command to manage the operations of its land, sea and air Self-Defense Forces, the Nikkei newspaper reported Saturday, as part of a major defense overhaul in the face of China's increasing assertiveness over Taiwan.

The government aims to have the joint command functioning by 2024. It will be tasked with coordinating strategies and boosting Japan's defense cooperation with the U.S. military, the Nikkei reported.

The Defense Ministry could not be reached for comment outside regular working hours.

Prime Minister Fumio Kishida's government is boosting its military spending in response to China's growing might and geopolitical uncertainty over Taiwan, as well as North Korea's missile and nuclear weapons development.

The new arrangements will be included in the defense overhaul that the government will unveil by the end of the year, Nikkei said.

The joint command will be overseen by a joint commander, a newly created position that will report directly to Japan's defense minister, it added.
