South Korea and Japan warned North Korea that it would face a strong response if it carried through with a threat to launch a missile toward Guam.
Gaminde's remarks comes after North Korea announced earlier on Thursday that the nation has a detailed plan for a missile strike near Guam, where about 7,000 United States troops are stationed, using four intermediate-range ballistic rockets.
According to the sources, the PAC-3 missiles will be placed in: Kaita, Hiroshima Prefecture; Izumo, Shimane Prefecture; Kochi, Kochi Prefecture; and Matsuyama, Ehime Prefecture. Aegis destroyers are equipped to intercept missiles in the middle of their trajectory while the land-based Patriot PAC-3 system is created to destroy them as they descend towards their targets.
The South Korean official said member states of ARF reaffirmed it shared the common goal of the global communities to "achieve a complete, verifiable and irreversible denuclearization of North Korea in a peaceful manner". The annual exercises, called Ulchi-Freedom Guardian, are expected to run from August 21 to 31.
Life on the streets of the North Korean capital, Pyongyang, also remained calm.
President Donald Trump on Friday again delivered a warning to North Korea, tweeting that the US military is "locked and loaded" if the isolated rogue nation acts "unwisely", escalating an exchange of threats between the nuclear-armed nations.
Mr Trump has said he would respond to any such action with "fire and fury".
New United Nations sanctions condemning the North's rapidly developing nuclear program drew fresh ire and threats from Pyongyang.
French President Emmanuel Macron called for the global community to work with North Korea to "resume the path of dialogue without conditions", following a call with Trump Saturday.
Asked if the US was going to war, he said cryptically, "I think you know the answer to that".
That same year, Congress passed the Organic Act of Guam, giving Guamanians American citizenship.
"Faith is so deeply rooted into our culture", he said. "In the President's words they are behind us '1,000 percent.' As the head of the Government of Guam, I appreciate their reassurances that my family, my friends, everyone on this island, are all safe".
Officials have not raised the territory's threat level even after Pyongyang laid out plans to strike near the island in the coming weeks, Guam governor Eddie Calvo said. Residents do not pay US income taxes or vote in the general election for USA president. Chamorros are the indigenous people of Guam. Since the end of the Spanish-American War in 1898, the largest and southernmost island in the Mariana Islands archipelago has been an essential part of USA power projection.
"Nobody really deserves to be caught in the middle of these games", said Victoria-Lola Leon Guerrero, an activist who campaigns for a lowered military presence.
