Beijing on Saturday accused German Foreign Minister Annalena Baerbock of "making unwarranted accusations" about China's actions during recent confrontations with Philippine ships in the South China Sea.

"The recent maritime incidents between China and the Philippines were not caused by China and China has taken necessary measures to safeguard its territorial sovereignty and maritime rights and interests," the Chinese embassy in Manila said in a statement on its Facebook page.

It also said: "No non-regional country has the right to interfere in the maritime disputes between China and the Philippines."

The statement added that China should not be blamed for recent incidents and is "committed to properly handling disputes with the Philippines through dialogue and consultation with the aim of jointly maintaining peace and stability in the South China Sea".

During Baerbock's recent visit to the Philippines - the first by a German foreign minister in about a decade - she said China was threatening freedom of navigation in the disputed waters and the dispute was a matter of concern for Germany and other European countries.

In recent months there have been repeated face-offs between Chinese and Philippine ships in the South China Sea, including several collisions that each side blamed on the other.

In some cases, Chinese ships used water cannons against vessels trying to resupply Philippine troops stationed on a disputed reef.

There are concerns that the dispute could escalate further and draw in the United States. Manila has moved to strengthen military ties with its long-term ally in recent months, including more joint exercises.

At a press conference with her Philippine counterpart Enrique Manalo on Thursday, Baerbock said: "[China's] risky manoeuvres violate the rights and economic development opportunities of your country and other neighbouring countries.

"For countries around the world, they call into question the freedom of the sea routes guaranteed under international law in an area through which a third of global maritime trade flows."

On Saturday, the Chinese embassy said there was "never any issue" with freedom of navigation in the South China Sea and blamed "the deliberate intervention of external forces intending to sow discord among regional countries".

Baerbock said it was "crystal clear" that China's claims "are not covered by international law".

But the Chinese embassy defended Beijing's decision to reject a 2016 ruling by an international arbitration panel that invalidated China's extensive territorial claims on historical grounds.

The embassy said it was "in essence a dispute of territorial sovereignty, which is beyond the scope of the United Nations Convention on the Law of the Sea and does not concern the interpretation or application" of the law.

"The so-called 'rules-based international order' is essentially a set of 'house rules' established by a few Western countries to contain and suppress other countries," the embassy said.

"China does not accept or recognise it, and will never accept any claim or action based on the [ruling]."
