A day after reiterating his commitment to denuclearization of the Korean Peninsula, North Korean leader Kim Jong Un has set out a timeline for the process, saying he intends to get the process done by the end of President Trump's first term in office.

Kim committed to a denuclearization earlier this year at a summit with South Korea, and a new inter-Korean summit is coming up in mid-September. The next summit is intended to focus on "practical measures" to advance the process.

North Korea is keen to have a peace treaty, ending the Korean War, as part of this process. The Korean War began in 1950, and the US has been resisting efforts to negotiate a peace treaty, saying the deal needs to wait until after denuclearizaiton.
