South Korea’s president has declared that Seoul will consider sending an envoy to North Korea should they cease their missile and nuclear tests.
Moon Jae-in also stated that there would be no war with the North:
"The people worked together to rebuild the country from the Korean War, and we cannot lose everything again because of a war," Mr Moon said in a nationally televised news conference.
"I can confidently say there will not be a war again on the Korean Peninsula."
Powerful rhetoric from both the US president Donald Trump and North Korean leader Kim Jong Un have also lead to heightened concerns.
Mr Trump tweeted on Wednesday that Kim Jong Un had: “made a very wise and well-reasoned decision," amid indications that he does not immediately plan to fire multiple missiles toward Guam.
Mr Trump wrote:
"The alternative would have been both catastrophic and unacceptable!"
However, next week will see the start of US-South Korean military exercises which have angered the North in the past.
This could make attempts at diplomacy between the two nations even more difficult.
