What measures should China take when the Philippines invades Huangyan Island?

If it is compulsory two, you can answer it from these aspects.

1, sovereignty, as the unified and indivisible supreme power of a country, is the life and soul of a country, so China must firmly safeguard its sovereignty and territorial integrity;

2. We should play the role of the United Nations in the Philippine invasion of Huangyan Island in China. The purpose of the United Nations is to maintain international peace and security and promote international cooperation and development.

3. Resolutely safeguard China's national interests, which is a country's right to survival and development, and also a decisive factor in international relations. Safeguarding one's own national interests is the starting point and the end result of a sovereign country's foreign policy.

4. Adhere to the independent foreign policy of peace and the basic stand of independence, and do not allow other countries to interfere in China's internal affairs and infringe on China's sovereignty and integrity.

It is better to have materials. If it is political common sense, I think of these.
