Prime Minister Tony Abbott says he is confident of securing a free-trade agreement with China within 12 months.

Speaking to the media at the APEC summit in Bali, Mr Abbott said he was using the meeting to shore up free trade with other countries in the region, particularly China.

Mr Abbott met with China's president Xi Jinping last night and has confirmed he will travel to China in the first half of next year.

"It would be wonderful if a trip towards the end of the first half of next year was consummated by an agreement here," he said.

"Our intention is to move as quickly as we can. I would be disappointed if we couldn't conclude a significant free-trade agreement with China in 12 months."

Mr Abbott pointed to a successful trade agreement between New Zealand and China.

"Lets face it, the Kiwis, have had a series of agreements, including one with China, which have been very good for their economy," he said.

"They've managed to go from start to finish much more quickly than we've been able to manage over the last few years under the former government and I think we can do a lot better than that now."

Mr Abbott also sought to give reassurances to both Australians and overseas investors that Australia welcomes foreign investment.

"Australia must always be open for business," he said.

He says he wants Australia to get its "fair share" of Chinese investment.

"We welcome foreign investment. It will be good for jobs. It will be good for economic activity. It should be good for Government revenue."

He says foreign investment has helped Australia throughout its history.

"Without British investment we wouldn't have the agricultural industry. Without American investment we wouldn't have the manufacturing industry," he said.

Mr Abbott also says negotiations are going well on a trans-Pacific partnership and a deal should be finalised by the end of the year.

Meanwhile, Mr Abbott issued a stern warning to activists protesting about the situation in Indonesia's disputed Papua region.

Three West Papuan protesters scaled the wall of the Australian consulate in Bali on Sunday seeking refuge and calling for the release of political prisoners.

Mr Abbott says after "lengthy discussions" discussions with consular staff, the activists agreed to leave.

"Now I want to make two fundamental points and I want to stress these points, I want to put them up in flashing neon lights," he said.

"Australia will not give people a platform to grandstand against Indonesia, we have a very strong relationship with Indonesia. I want that to be absolutely crystal clear.

"Second point I make is that the situation in West Papua is getting better not worse and I want to acknowledge the work that president Yudhoyono has done."

Mr Abbott says Australia respects Indonesia's "territorial integrity".

"The people of West Papua are much better off as part of a strong, dynamic and increasingly prosperous Indonesia," he said.

Mr Abbott is due to meet leaders from Canada, Thailand, Singapore and Mexico before the official APEC program begins tomorrow.

There will be a gala dinner for leaders held tonight.
