Local governments of Japan and Russia have discussed marine plastic pollution and agreed to cooperate in addressing the problem.
They held an online conference on Wednesday as part of a campaign to promote regional exchange between the two countries.
Officials from five Japanese local governments, including the cities of Osaka and Sakata, and Russia's second-largest city St. Petersburg took part in the event.
Marine plastic pollution is seen as a global challenge that has become increasingly serious in recent years.
Osaka Mayor Matsui Ichiro said in a video message that he's glad regional communities can exchange ideas on the internationally important issue.
Another official from Osaka reported resident-led efforts to reduce plastic waste, such as collecting plastic bottles in each of the city's school districts.
An official from St. Petersburg cited the growing seriousness of plastic pollution in the sea, and called for more powerful legislation in the country.
