South Korea has considered lifting economic sanctions created to force North Korea to relinquish its nuclear weapons, drawing a swift rebuke from Donald Trump and exposing a rift in Seoul's alliance with Washington.
Mr Trump has hinted that he is ready to declare an end to war with Pyongyang, formally closing the 1950-53 conflict that resulted in an armistice rather than a formal treaty.
"The North Korean economy is on the verge of collapse and they wouldn't have a lot of choice if the United States and South Korea dictated certain terms", Mr Kang said. The two leaders agreed to hold the second meeting "at the earliest possible date".
"We can see that sport is being used as an extension of politics - it is an important political tool that is being used here by North Korea and Beijing", said James Floyd Downes, a lecturer in comparative politics at the Chinese University of Hong Kong. Pompeo returned from meetings with Kim this week, claiming "significant progress", but also added, "there are many steps along the way and we took one of them today".
Kim allegedly told Moon during their summit in Pyongyang last month that he will "ardently welcome the pope if he visits Pyongyang".
"I've never been involved in an worldwide discussion where there weren't differences of view, not only between governments but inside of governments", he said.
Kenneth Bae, a Korean-American evangelist who ran Christian tours of North Korea, was sentenced to 15 years of hard labour in 2013 for "anti-government" crimes.
Senior North Korean officials including sports minister Kim Il-guk and foreign affairs minister Ri Su-yong were also at the game. "So it was not an easy task for me". Kim is said to have "passionately welcomed" the idea.
"He didn't even want to know what I was going to say before the speech". South Korea has blamed North Korea for the attack, which the North continues to deny. More than 10 million North Koreans, almost 40 percent of the population, are undernourished and need humanitarian aid, it said.
North Korea also takes a dim view of foreign missionaries.

North Korea is under a series of global economic sanctions approved by the U.N. Security Council after Kim and his predecessor father Kim Jong Il conducted nuclear and missile tests. Former chief US diplomat for East Asia, Daniel Russel told NBC: "Did Mike Pompeo go all the way to Pyongyang for party planning purposes?"
The president stressed the need for the North to take actual denuclearization steps before his country or the worldwide community could start considering removing their sanctions on the impoverished North.
In a rare sign of discord between Seoul and Washington, Kang said on Wednesday that U.S. Secretary of State Mike Pompeo had expressed "discontent" with an inter-Korean military pact reached during a summit last month.
Rolls Royce, of course, is a British luxury vehicle maker, and North Korea remains under heavy United States sanctions that strictly forbid the sale of luxury goods to the country.
He added that worldwide inspectors could soon be arriving at two North Korean nuclear sites.
Trump said Tuesday that the two sides are working to arrange a summit after the November 6 midterm elections in one of three or four locations. "I look forward to seeing Chairman Kim again, in the near future", he said.
