BEIJING (REUTERS) - China and Japan on Friday (Oct 26) pledged to forge closer ties as both countries stood together at an "historic turning point", signing a broad range of agreements including a US$30 billion (S$41.5 billion) currency swap pact, amid rising trade tensions with Washington.

Japanese Prime Minister Shinzo Abe and Chinese Premier Li Keqiang also agreed the two countries would work together to achieve denuclearisation on the Korean Peninsula.

The pacts were reached on Abe's three-day visit to Beijing as the two neighbours looked to carve out new areas of cooperation and seek new ways to promote trust, which has been fragile at times since diplomatic relations resumed in 1972.

Chinese Premier Li Keqiang said 500 business deals worth US$18 billion (S$25 billion) had been signed between Chinese and Japanese companies during the visit, a reflection of the "bright prospects" for cooperation between the two countries.

"From competition to co-existence, Japan and China bilateral relations have entered a new phase. Hand in hand with Premier Li, I would like to advance our ties forward," Abe told reporters after the pair met on Friday morning.

Both countries are neighbours and partners, and will not become a threat to each other, Abe said after meeting President Xi Jinping on Friday in the first full-scale Sino-Japanese summit since 2011.

"With President Xi Jinping, I would like to carve out a new era for China and Japan," Abe said.

Xi said bilateral ties had returned to the right track and China would ensure the positive momentum continues, according to state media.

"That is worth cherishing by both sides," Xi said.

Both sides should undertake more in-depth strategic dialogue, Xi said, adding that exchanges between ordinary Japanese and Chinese people should also be stepped up to foster deeper mutual understanding.

"Both sides should accurately grasp each other's strategic intent, and implement what was agreed - that both sides will become partners, both sides will pose no threats to each other," Xi said.

TERRITORIAL DISPUTE

Abe returned to power in 2012 when Sino-Japanese ties were in tatters due to a feud over East China Sea islands, and the territorial dispute remains a key source of friction between the two countries.

Deputy Chief Cabinet Secretary Yasutoshi Nishimura told reporters in Beijing that Abe told Li during their meeting that there would be "no genuine improvement" in bilateral ties unless there was "stability in the East China Sea".

Japanese firms including big auto companies like Toyota hope to see normalised ties with China so they can compete with US and European rivals, while Beijing expects Tokyo's endorsement of its ambitious Belt and Road programme, an initiative that Xi hopes will further boost trade and transport links with other countries.

Abe also said Tokyo was "determined" to normalise diplomatic relations with Pyongyang, but only if preconditions were met, including denuclearisation and the release of kidnapped Japanese citizens.

"Our two countries bear large responsibility in achieving peace and stability in this region," Abe said.

Efforts in advancing China-Japan ties should "persevere unremittingly to prevent the appearance of new twists and turns" so that previous efforts did not go to waste, said Li at a joint briefing with Abe on Friday.

"The Chinese side is willing to work with the Japanese side to return to a normal track, and maintain the stable, sustained and healthy development of bilateral relations," he said, adding that he had held candid discussions with Abe since his arrival on matters of mutual concerns.

They reached consensus, Li said, that safeguarding long-term healthy and stable China-Japan ties was in accordance with the interests of both countries, the region and the world.

The move to boost economic ties came as China and the United States slap tit-for-tat tariffs on each other in recent months.

Japan is at risk as it exports to China manufacturing equipment and electronic parts, which are used to make finished goods for the US and other markets.

While Japan, worried about China's growing naval power, is keen for closer economic ties with its biggest trading partner, it must manage that rapprochement without upsetting its key security ally, the US, with which it has trade problems of its own.

Ahead of the briefing, China and Japan signed an agreement to prepare yearly plans for talks, dialogues and exchanges, as well as a pact to step up cooperation in innovation.

They also agreed to boost cooperation in the securities markets including the listing of exchange-trade funds (ETFs), and facilitate smoother customs clearance.

The sides signed a currency swap agreement of up to 3.4 trillion yen (S$42 billion), effective until 2021.

They also inked a deal towards establishing a yuan clearing bank.

Li said both sides had agreed that as major countries, China and Japan should uphold free trade and accelerate talks on the Regional Comprehensive Economic Partnership (RCEP) and on a China-Japan-Korea trade zone.

RCEP is an Asean-led free trade pact comprising 16 countries, including Japan and China. The 16 countries have resolved to conclude the pact by the end of the year.
