Japan pressed China to improve its climate for foreign businesses during talks Saturday between the world's number two and three economies that also touched on the issue of North Korean disarmament.
Foreign Minister Katsuya Okada led a delegation to Beijing for talks with a Chineseside led by Vice Premier Wang Qishan in which both urged even greater cooperation between their two increasingly inter-connected economies.
"The economies of both countries highly rely on each other," Wang told the Japanese delegation, later saying after the third Japan-China High-level Economic Dialogue that the talks were "fruitful."
Behind the calls for cooperation, Japan became the latest of China's trading partners to complain about the country's business environment.
Japanese firms have borne the brunt of recurring labour disputes at foreign-established factories in China this year, and officials said Okada pressed Beijing for more "transparent" labour policies.
"The Japanese side asked China to improve the business environment and exchanged views in this regard," Okada said after the meeting.
A Japanese government spokesman later said China attributed the labor unrest to a "natural" push for better wages.
"Japan is not satisfied with this," said the spokesman, Satoru Satoh.
China's economy outpaced Japan in the second quarter in nominal terms. The two countries are numbers two and three, behind only the US.
China has heard a chorus of complaints by European and US businesses and officials over perceived unfair policies and market restrictions hurting foreign enterprises.
Okada told his counterpart Yang Jiechi that Tokyo was against an early restart of six-nation talks hosted by China on dismantling North Korea's nuclear programmes, Satoh said.
