Former U.S. presidential candidate Hillary Clinton said on Wednesday that "cavalier" threats to start war on the Korean peninsula were "dangerous and short-sighted", urging the United States to get all parties to the negotiating table.
Clinton also called on China to take a "more outfront role" in enforcing sanctions against North Korea aimed at curbing its missile and nuclear development.
"There is no need for us to be bellicose and aggressive (over North Korea)," Clinton told the World Knowledge Forum in the South Korean capital of Seoul, stressing the need for more pressure on North Korea and diplomacy to bring Pyongyang to talks.
Tension between Pyongyang and Washington has soared following a series of weapons tests by North Korea and a string of increasingly bellicose exchanges between U.S. President Donald Trump and North Korean leader Kim Jong Un.
"Picking fights with Kim Jong Un puts a smile on his face," Clinton said, without mentioning Trump by name.
Clinton also indirectly referred to Trump's social media comments on North Korea, saying, "The insults on Twitter have benefited North Korea, I don't think they've benefited the United States".
The war of words has seen Trump call the North Korean leader "little rocket man" on a suicide mission, and vow to destroy the country if it threatens the United States or its allies. In turn, the North called Trump "mentally deranged" and a "mad dog".
