"We're willing to work with South Korea to preserve the hard-won results, properly handle disputes, put China-South Korea relations back onto a normal track and benefit both peoples on the basis of mutual understanding and mutual respect", he said. North Korea's testing of the new missile system may make it more hard for Moon to follow along the path of reconciliation, However, in his first key appointments Moon appointed supporters of the earlier Sunshine Policy of improving ties with the North, to the positions of prime minister and head of intelligence.
U.S. President Donald Trump told South Korea's presidential envoy that Washington was willing to try to resolve the North Korean nuclear crisis through engagement, but under the right conditions, South Korea's foreign ministry said on Thursday.
Before leaving Seoul for Beijing, Lee said Moon could meet Xi as early as July at a Group of 20 summit in Germany, while a separate meeting could also be possible in August.
Chinese official media quoted Xi as saying China is committed to resolving any issues through dialogue and coordination.
A US Navy commander on Wednesday pushed for a "sense of urgency" over North Korea's nuclear and missile development, stressing that it even threatens Pyongyang's ally China and neighbour Russian Federation.
Lee said the Moon administration is "ready to bolster dialogue and enhance mutual understanding".
Last month, Washington also positioned THAAD anti-ballistic missile systems in South Korea, which is aimed to protect the country from attacks by its communist neighbor. China is North Korea's biggest economic partner and source of diplomatic support and has come under heavy pressure to use its influence to rein in the North's missile and nuclear activities.

Hospitals have stopped diverting patients following last week's cyber attack which crippled many NHS Trusts' IT systems. Experts and authorities have told users, if hit, to not pay the attackers' ransom.
China's Foreign Ministry also said Xi reaffirmed the country's commitment to a nuclear-free Korea and the resolution of the issue through dialogue and negotiations, in line with Moon's pursuit.
Wang on Thursday reiterated calls for its dismantling.
In recent weeks Beijing and Seoul have signaled a desire to fix relations following the election of Mr. Moon, who has taken a friendlier stance toward China than his conservative predecessor. Although he has sometimes criticized the THAAD deployment, Moon has not said he will remove it.
President Xi Jinping sent a congratulatory telegraph to Moon on May 10 and held a phone conversation with him a day later.
Russian Federation and China have opposed the THAAD deployment, calling on the all parties to find a peaceful solution to the hazardous situation in the region. Hong said South Korea had not yet received official word from the United States on whether Seoul should pay for an anti-missile U.S. radar system that has been deployed outside Seoul.
In what both governments hoped was a major step forward, the two countries had agreed in 2015 to a deal created to end a row over Korean "comfort women" forced into sex slavery for Japanese soldiers during the World War II.
