The 27-member bloc will set out a formal strategy to boost its presence in the region but Australia's decision to cancel submarine deal with France may complicate cooperation.
The European Union will set out a formal strategy to boost its presence in the Asia-Pacific and counter China's rising power, although Australia's decision to cancel an arms contract with France may complicate cooperation, diplomats said.
Led by France, Germany, and the Netherlands, which first set out ways to deepen ties with countries such as India, Japan and Australia, the 27-member bloc wants to use the plan on Thursday to show Beijing that it is against the "spread of authoritarianism."
However, Wednesday's agreement between the United States, Australia, and Britain to establish a security partnership for the region and scrap a $40 billion French-designed submarine deal has damaged trust between allies, French Foreign Minister Jean-Yves Le Drian said.
A spokesperson for EU foreign policy chief Josep Borrell said the bloc had not been informed about the security partnership and was trying to find out more.
"We will have to discuss with member states to assess the implications," Peter Stano told a regular news briefing.
Plan to antagonise China
Following an initial plan in April, the EU will set out in detail how it plans to deepen ties with its allies in environmental, trade, and digital policies, as well as seeking to develop a maritime presence to keep trade lanes open.
Diplomats said the plan was not "anti-China", although envoys in Brussels acknowledge that Beijing is likely to see it that way as tensions over contested territories and maritime zones grow, as well as concerns about China's military build-up.
"The display of force and increasing tensions in regional hotspots such as in the South China Sea and in the Taiwan Strait may have a direct impact on European security and prosperity," according to an earlier, draft version of the plan.
Mixed strategy towards Beijing
The plan may mean a higher EU diplomatic profile on the region issues, more EU personnel, and investment in the region and a security presence such as dispatching ships through the South China Sea, or putting Europeans on Australian patrols.
Separately, the European Parliament on Thursday voted 570 in favour, 61 against, with 40 abstentions, to press EU governments for a mixed strategy towards Beijing, combining cooperation on trade and health while fighting alleged Chinese human rights abuses.
