China and South Korea should begin "a journey of trust" that opens up the next 20 years after two decades of economic success, South Korean President Park Geun-hye said yesterday.
The two nations should build a more mature and substantial partnership, Park told 500 students at Tsinghua University in Shanghai - Chinese president Xi Jinping's alma mater - on the third day of her of her visit.
"I intend to pursue dialogue and co-operation in a more forward-moving way based on the deep trust forged with President Xi through the summit," she said.
On Thursday, they pledged to work closely to free the Korean peninsula from nuclear arms, which were held only by the North.
"Beyond the successful Korea-China relations over the past 20 years, I intend to begin a journey of trust that opens up a new 20 years," said the leader, who began her 20-minute speech with some remarks in Chinese.
Park said she was ready to help North Korea revive its economy if Pyongyang gave up its nuclear weapons programme.
She said a peaceful Korean peninsula would also benefit Chinese provinces sharing a border with North Korea.
Before her university visit, Park used a meeting with Vice-Premier Liu Yandong to offer the return of the remains of hundreds of Chinese troops killed in the 1950-53 Korean war, Yonhap said.
Park also flew to Xian in Shaanxi province to meet provincial leaders and visit major South Korean investment projects, including a US$7 billion Samsung Electronics chipmaking complex.
