The government on Tuesday adopted an action plan aiming to invest a total of ¥1 trillion across the public and private sectors by 2030 to secure recycled resources.The plan is designed to promote the reuse of discarded plastics and metals amid intensifying international competition for resources as China tightens restrictions on exports of rare earths to Japan.'It is important to promote public-private investment, accelerate the transition to the circular economy, and link the initiative to the (Prime Minister Sanae) Takaichi administration's growth strategy aimed at realizing a strong economy,' Chief Cabinet Secretary Minoru Kihara said at a meeting of relevant ministers.
