"We hope that under the leadership of President Xi Jinping, our relations can be continued in a bid to develop the welfare of people both in Indonesia and China in the future," Marzuki told Xinhua.

Marzuki said that China expects Indonesia to serve as the center of China's relations with other countries in Southeast Asia.

Indonesia posted record-high 12 billion U.S. dollars export to China in the first seven months this year.

"When I met Chinese premier last year during my visit in that country, he said that China wanted to advance further along with Indonesia, would not live on surplus it gained from Indonesia. China ready to help increasing Indonesia's capacity and opening more of its domestic markets for Indonesian products," Marzuki said.

He added that the planned Chinese investment increase was the most concrete move demonstrated by Chinese government to respond this issue. Marzuki said that the plan was discussed in the recent meeting of Indonesian President Susilo Bambang Yudhoyono and his Chinese visiting counterpart.

"We must support what have been conducted by President Susilo Bambang Yudhoyono and President Xi Jinping," Marzuki pointed out.

He said that China's investment in Indonesia now stood at 2.22 billion U.S. dollars. Reports said that 32.8 billion U.S. dollars worth of new Chinese investments in Indonesia are ready to be signed in the upcoming Asia Pacific Economic Cooperation (APEC) leaders meeting in Indonesia's Bali.

Milton Pakpahan, a legislator at the parliament's Commission VII for energy issue said that Indonesia provides abundant of resources and China has the technology and industry.

"We are perfectly depended to each other. We have something that beneficial to them. Should they open their investments here, it would be more efficient. In our side, it would create jobs that eventually would increase welfare to both countries," Milton, a legislator from the ruling Democrat Party, told Xinhua.
