On 10 June 2016, the Daily Telegraph and its website published a signed article by Ambassador Liu Xiaoming entitled "Stop playing fire in the South China Sea". The full text is as follows:

Away from Britain’s focus on the forthcoming EU referendum, a serious international situation is developing in the South China Sea region. Although little reported in the UK, there is now much discussion about whether China should accept the ruling of the South China Sea arbitration process.

Proponents of this idea claim that China’s rejection would "undermine" the "rule-based international system" and would put the peace and stability of the region "under immediate threat". We disagree.

It is important to understand that this arbitration process was in fact started by the Philippines unilaterally as an attempt to legitimise their illegal occupation of the Nansha islands and reefs.

Unknown to most of the British public is the fact that more than 40 of China’s islands and reefs in Nansha are illegally occupied by the Philippines and some other countries, who have built airstrips and deployed weapons there. The Philippines in particular has kept provoking disputes over islands and reefs time and again by, for example, "grounding" a warship forcibly and illegally on China’s reef to lay its claim.

China responded with maximum self-restraint, appealing for negotiations and consultations. We have called for disputes to be shelved and for joint development pending the ultimate solution of the issue.

However, it now appears that the Philippines sees China’s self-restraint as being weak. It has therefore gone one step further. It not only wants Chinese islands and reefs but has also filed for arbitration to drape its illegal occupation in the cloak of law.

Yet the tribunal has no jurisdiction over the case at all. The submissions made by the Philippines appear to be related only to the classification of maritime features and fishery disputes, but are in essence inseparable from territorial sovereignty and maritime delimitation.

Territorial sovereignty is not within the scope of the UN Convention on the Law of the Sea (UNCLOS), whose preamble states that it establishes a legal order for the seas and oceans "with due regard for the sovereignty of all States". China made a clear declaration in 2006 in accordance with UNCLOS to exclude maritime delimitation from compulsory arbitration. More than 30 other countries, including Britain, have made similar declarations.

Despite the fact that this tribunal has no jurisdiction over either territorial sovereignty or maritime delimitation, the Philippines has abused its right of action by knowingly initiating an unlawful case.

The tribunal meanwhile has abused its right of competency by knowingly accepting a case that is clearly not within its jurisdiction.

Tom Zwart, a law professor at Utrecht University, warned in a recent article that in East Asia, "the [arbitration] award will be widely regarded as the fruit of a poisonous tree, and it will fail, therefore, to garner the necessary support".

Such a view is shared by numerous international law experts around the world. China’s non-participation in the arbitration process upholds international law.

The Law of the Sea clearly provides for a bilateral approach prior to any third-party mechanism, including arbitration. Yet it is clear that bilateral options between China and the Philippines have not been exhausted. The tribunal’s imprudent decision to start the compulsory arbitration process suggests a lack of even minimal respect for the spirit and principles of the UNCLOS to say the least.

Would anybody go into a football match where the rival team has conspired with the referee? Of course not. The fans and audience would not accept it.

The "wirepuller" behind the arbitration is self-evident. For years this country from outside the region has been stepping up its rebalancing strategy in the Asia Pacific.

Its politicians have been making provocative remarks when talking about its Asia Pacific policies and the South China Sea issue, and its military has invested massively in the South China Sea region and areas around it.

The arbitration is in fact its carefully drafted show; the Philippines is merely reading the script.

Ironically, while pointing the finger at others and labelling China as "not abiding by international law" in the name of protecting UNCLOS and the international law, this country seems to have forgotten that it has itself refused to sign UNCLOS.

There is a quote from the Bible which neatly sums up the situation: "Why do you look at the speck in your brother’s eye, but fail to notice the beam in your own eye?"

My advice for the Philippines is to return to a negotiated solution, and for some countries from outside the region to stop playing with fire.

The parties directly involved in the South China Sea should consult and negotiate face to face, drawing on historical facts and international law. This is the only way we will resolve the South China Sea issue, restore harmony, and bring about lasting peace, cooperation and prosperity to this region.
