The president said Jakarta will safeguard its sovereignty in the contested waterway days after signing a maritime deal with Beijing.

BEIJING, Nov 10 (Reuters) - China and Indonesia signed deals worth $10 billion at the Indonesia-China Business Forum in Beijing on Sunday, spanning sectors including food, new energy, technology, and biotechnology, Chinese state media reported.

Over the weekend, the two nations signed a joint development agreement that refers to “overlapping claims” in the disputed waterway.

Indonesia denied that it had effectively recognized China’s disputed claims in the South China Sea after a joint statement with Beijing over developing contested areas came under fierce criticism.

Indonesia said on Monday it does not recognise China's claims over the South China Sea, despite signing a maritime development deal with Beijing, as some analysts warned the pact risked compromising its sovereign rights.

The deals included a controversial agreement on economic activities in areas around the Natuna Islands in the South China Sea.
