His remarks came days after North Korea conducted its sixth nuclear test.
During the phone call, Xi and Trump exchanged their views on the current situation on the peninsula.
Xi said China had been adamant in preserving international nuclear non-proliferation, maintaining peace and stability on the peninsula, and resolving the nuclear issue through talks, state-run Xinhua news agency reported.
The Chinese president said the general direction should head toward a peaceful settlement of the issue, adding that dialogue combined with a set of comprehensive measures is best for seeking a long-term solution.
He pledged to step up communication with the Chinese side in a bid to find a solution as early as possible.
Also during the talks, Xi said China attaches great importance to Trump's visit to China later this year, hoping both sides can work together to ensure the visit a success.
