Prime Minister Shinzo Abe and U.S. President Donald Trump agreed Friday to cooperate over their countries' coronavirus response and development of treatment drugs and vaccines, a top Japanese official said.

During phone talks held at Japan's request, Abe and Trump also explained efforts being made by their countries to contain COVID-19 and toward resuming economic activities, Chief Cabinet Secretary Yoshihide Suga said at a news conference.

"It was very meaningful that the Japanese and U.S. leaders confirmed coordination via phone talks at a time when global unity is being required (to fight the coronavirus)," Suga said.
