SEOUL, South Korea - With diplomatic relations hitting an impasse, months after his meeting with the North Korean leader Kim Jong Un, the U.S. President Donald Trump sought to overcome the key hurdles last week.

On Monday, the South Korean President Moon Jae In revealed that Trump had charged him with delivering a key message to his North Korean counterpart.

Speaking to reporters, Jae In said that Trump had asked him to forward a message to the North Korean leader, which was aimed at ending the snag in talks between Pyongyang and Washington and would pave the way towards swift denuclearization of the Korean Peninsula.

The South Korean President said, The message was that President Trump has a very friendly view of Chairman Kim and that he likes him, and so he wishes Chairman Kim would implement the rest of their agreement and that he would make what Chairman Kim wants come true."

Jae In said that Trump discussed the state of affairs with him during a meeting held on the sidelines of the Group of 20 Summit in Argentina last week.

Sanctions Vs. Missiles

Since Trump's meeting with Kim Jong Un in June this year, when the two leaders vowed to deliver peace on the Korean Peninsula by charting a path towards complete denuclearization of the Korean Peninsula - the subsequent rounds of diplomatic talks between the two countries have failed to deliver concrete results.

While North Korea has insisted on receiving relief from the strict international sanctions against the country before it denuclearizes, the U.S. has demanded verifiable dismantling of the country's nuclear arsenal before it lifts the sanctions.

Pyongyang has also repeatedly slammed Washington's unilateral demand that the country destroys all its nukes.

Talks between the two countries are being headed by the U.S. Secretary of State Mike Pompeo, who has failed to deliver in getting a list of steps that the rogue nuclear nation aims to take towards denuclearization.

Pompeo has demanded that the nation hands over an inventory of the weapons that make up its nuclear arsenal, that has emerged as a major threat not only in Asia, but also for the rest of the world.

Meanwhile, experts have revealed that despite engaging in diplomatic talks, North Korea has continued to expand its ballistic missile program.

The Washington think tank, theCenter for Strategic and International Studies, has revealed that North Korea has continued to strengthen its missile development at several secret bases.

With talks deadlocked, North Korea even announced the test of a new ultramodern tactical weapon earlier this month.

Korean ties strengthen

While Washington and Pyongyang fail to move past the impasse, the two Koreas have enhanced ties over the last few months.

Despite stringent UN sanctions, South Korea has been pacing ahead with an ambitious project to connect the daily networks between the two countries.

On Friday, for the first time in over a decade, a South Korean train crossed the heavily-guarded border into North Korea.

Further, experts from Seoul announced that they had begun surveying railway tracks in the North.

The first train to cross the border in several years on Friday required a special permission from the UN to carry equipment and fuel into the North.

Separately, the South Korean leader announced that Kim Jong Un was likely to visit Seoul before the end of the year - in what would become the first time a North Korean leader visits Seoul since the end of the Korean War of 1950-1953.

Meanwhile, Jae In indicated in his statement to reporters that corresponding measures might be given for steps that North Korea takes towardcompletely dismantling its nuclear weapons program.

However, he categorically clarified that these measures do not have to include sanctions relief that Pyongyang has been desperately seeking in a bid to strengthen its economy.

Shedding light on the possible measures, Jae In said, For example, postponing or reducing the U.S.-South Korean joint military exercises may be a sort of corresponding measure, or humanitarian assistance, or some kind of non-political exchange, whether it is a sports exchange or an art troupe."
