Joe Biden has firmly denied that the United States is discussing whether to hold joint nuclear exercises with South Korea - and contradicted its leader.
South Korean President Yoon Suk-yeol had been reported as saying that US officials were “quite positive” about the possibility of joint military exercises involving nuclear weapons.
The US and South Korea have been working together over the common threat they see from North Korea and it included jointly test firing surface-to-surface missiles last October.
