On Wednesday, the United States (US), Japan and South Korea agreed to issue a stern warning to retaliate if North Korea continues its efforts to conduct a seventh nuclear bomb test.
They believe that North Korea will carry out their nuclear bomb test since the last time in 2017.
South Korea's First Vice Foreign Minister Cho Hyun-dong announced at a press conference in Tokyo that they agreed to retaliate against North Korea's actions if they persist in carrying out the nuclear bomb test.
Wendy Sherman, the US Deputy Secretary of State, said anything that happened like a nuclear bomb test by North Korea would have the effect of threatening global security.
North Korea has carried out many of its weapons tests this year, firing more than two dozen ballistic missiles, including one that passed through Japanese airspace as previously reported.
Japanese Vice Foreign Minister Takeo Mori said they agreed to cooperate in strengthening defense and maintaining security between the three countries.
