Japanese Prime Minister Shinzo Abe and South Korean President Park Geun-hye agreed on Monday to closely cooperate regarding North Korea's latest ballistic missile launch, the Japanese government said in a statement. 
Abe and Park confirmed their cooperation during a meeting on the sidelines of the G20 summit in the eastern Chinese city of Hangzhou, the statement said. 
Both leaders agreed that Tokyo and Seoul should coordinate well over North Korea both bilaterally and through the UN Security Council, Japan's news agency (Kyodo) reported. 
Their statement took place after North Korea fired three ballistic missiles into the Sea of Japan on Monday, the latest in a string of launches in recent weeks and months.
