The minister said Indonesia would continue to advocate for the completion of a code of conduct between the Southeast Asian bloc ASEAN and China on the South China Sea and prioritise ASEAN's centrality. 

Indonesia considers itself not a party in disputes over the sea, a waterway crucial to global trade, but has recently been tested by forays by China's coast guard into its exclusive economic zone. 

Beijing claims sovereignty over almost the entire South China Sea, putting it at odds with Malaysia, Vietnam and the Philippines, with disputes frequent over the conduct in their EEZs of China's massive fleet of coast guard. China insists it is operating lawfully in its territory. 

"In the geostrategic sense, Indonesia is close to a source of regional conflict, the South China Sea. Indonesia's position remains prioritising conflict resolution that is peaceful," Sugiono said, adding Indonesia would keep pushing for constructive dialogue on a code of conduct. 

Regional commitments to draft a code were first made in 2002 but talks towards its creation only started in 2017 and progress has been limited, with years spent discussing the framework for negotiations and numerous agreements signed to expedite the process. 

Thorny issues include whether the code will be legally binding, enforceable and based on international maritime law, under which a 2016 international arbitration panel ruled Beijing's expansive territorial claims had no legal basis. 

China does not recognise the ruling. 

In a wide-ranging speech setting out Indonesia's foreign policy that was attended by the diplomatic community, Sugiono also said Indonesia would prioritise completion of talks on free trade agreements and expand its international trade, including with non-traditional partners in Africa and the Pacific. 

He said Indonesia's joining the BRICS grouping - which includes Russia, China, Brazil, India, Iran, Egypt and South Africa - was not a deviation from Indonesia's international position, but an underlining of its free and active foreign policy. 

He also said Indonesia would never abandon its support for the Palestinian cause, calling for a ceasefire and accountability for Israel over its role in the Gaza conflict.

Sugiono was appointed in October when new President Prabowo Subianto took office. 

Earlier this week, Brazilian foreign ministry said in a statement that Indonesia is now a full member of BRICS and that the country "shares with the other members the will to reform the institutions of global governance and contribute positively to cooperation within the Global South".

Indonesia in turn said it "welcomes" the announcement of its inclusion.

"This achievement shows Indonesia's increasingly active role in global issues and commitment to strengthening multilateral cooperation to create a global structure that is more inclusive and fair," the Ministry of Foreign Affairs said in a statement on Tuesday.

BRICS was created in 2009 by founding members Brazil, Russia, India and China. South Africa joined the following year.

The bloc was expanded again last year with Iran, Egypt, Ethiopia and the United Arab Emirates becoming full members.

Indonesia sees its BRICS membership as "a strategic step to improve the collaborations and cooperation with other developing nations, based on the principle of equality, mutual respect, and sustainable development", the Jakarta statement said.
