The reason why the Phnom Penh government (the puppet regime) agreed to the United Nations to intervene in mediation is mainly related to the huge disparity in national strength between China and Vietnam. In the early years, when China and Vietnam fought the two-mountain battlefield, the Vietnamese were beaten to a complete body, whether it was the army or the air force, they all suffered heavy losses, and even the Vietnamese army could not approach within 40 kilometers of the border between the two mountains, once the Vietnamese reinforcements entered this "buffer zone", I don't know how the Chinese found out, and then the fierce artillery fire would hit and crush the Vietnamese.

The situation is similar in the South China Sea, where the Chinese rabbits have used the tactics of besieging islands in the dark, and the supply of the outlying islands occupied by Vietnam in the South China Sea has been cut off by the Chinese navy, and the soldiers on the islands are either dying of thirst and starvation, or committing suicide or surrendering, and Vietnam has no way at all.

China's military operations to Malaysia and Taiwan have proved one thing, that is, China's military strength is definitely not something that Vietnam can contend with, and if China is determined to work the Cambodian issue, then the Phnom Penh government will definitely not end well. Vietnam, which is facing difficulties externally, cannot take good care of the Phnom Penh government at this time, so it is no wonder that the Phnom Penh government has begun to find its own way out.

In addition, although China did not directly support the three factions of the people and Cambodia (Sihanouk, Khieu Samphan, and Song Shuang), with the help of the hands of the Nanyang State, it sent a lot of weapons to Sihanouk and other people and Cambodian armed forces, and even some military advisory groups gave them guidance in the armed forces of the people and Cambodia, which has already put considerable pressure on the Phnom Penh government, and the Phnom Penh government is not confident that it can completely rely on force to solve the rebellion, so it has no choice but to seek a political solution.

After arriving in Kampong Son, the first thing the Chinese-led UN peacekeepers did was to pacify the refugees, many of whom had been displaced by the war, and Cambodia's civil war had also brought great trauma to the country. In the spirit of humanitarianism, the rabbit family appealed to all countries in the world to provide assistance to the refugees in Cambodia and provide them with necessary material assistance.

However, taking this opportunity, the rabbit family also made a small fortune, some countries donated cash, and the rabbit family took it in exchange for tents, medicines and other materials in the country, and then shipped to Cambodia, although the amount is not particularly large, but it can be regarded as benefiting the country's industrial and commercial industry.

The main mission of the peacekeeping force is actually a diplomatic mission, not mainly for the purpose of fighting, so the first principle of the United Nations peacekeeping force is not to take the initiative to fight, not to get involved in any side of the conflict, and to use force only for self-defense. Upon arrival in Kampong Son, the principal officials of the Mission, including the Mission and the Blue Hats, began to extend invitations to the three parties, as well as the Phnom Penh government and the Vietnamese garrison, to come to Kampong Son for a discussion of the situation.

After all, the banner of the United Nations is still relatively easy to use, and even if the Vietnamese were unruly, they finally sent a relatively senior military officer, Le Zhen, to participate in the meeting. However, the meeting was not very constructive, and the commander of the peacekeeping force, Chinese Colonel Long Xin, bluntly conveyed the resolution of the UN General Assembly: "We demand that the Vietnamese side unconditionally withdraw its troops from Cambodia in order to respect Cambodia's national sovereignty and territorial integrity, and to abandon the improper idea of interfering in Cambodia's internal affairs, so as to effectively and effectively maintain regional peace and stability......"

This kind of officialdom is naturally good at Longxin, and before going abroad, they have all received diplomatic training, and they are no worse than real diplomats when they speak. However, the Vietnamese officer Le Trần lacked such training in diplomatic rhetoric disputes, and wanted to say something to refute it, but he was so desperate that he did not say a few logically complete words to prevaricate Long Xin, which made them even more unjust.

The Vietnamese did not stay in Kampong Son for many years, nor did they talk about being gray, nor did they say anything cruel, so they left so strangely. The departure of the Vietnamese also made Cambodia's chances of reconciliation a little slimmer, but Colonel Long Hin later said in an interview with Western journalists: "...... A red line must be drawn for Vietnam, and there are some things that can never be negotiated and traded, such as Cambodia's sovereignty and territorial integrity. Our peacekeepers uphold the resolutions of the United Nations Security Council and the General Assembly, that is, Vietnam must withdraw from Cambodia unconditionally no matter what, and the Cambodian problem must be resolved by the Cambodians themselves. ”

A Western journalist who doesn't like China very much: "In this incident, China took the initiative to intervene in Cambodia's affairs by using its military strength and political influence, is it a manifestation of interference in the internal affairs of other countries?" ”

Long Xin replied without leakage, and even wiped out, and said: "First of all, I need to express my dissatisfaction with the unprofessionalism of this journalist friend, China does not interfere in the internal affairs of other countries, but this peacekeeping operation is not carried out alone in the name of China, our peacekeeping soldiers here are not only Chinese, but also Canadians, Brazilians, Pakistanis, etc., we are in accordance with the instructions of the United Nations Security Council, in order to maintain peace in Southeast Asia and settle disputes, not China violates principles to interfere in the internal affairs of other countries." Without this clarity, I am afraid that this journalist friend is not a competent political journalist. ”

A group of Western reporters did not find any bones in Longxin, but some resentful fellows wrote some reports saying that China's foreign-related military personnel lacked politeness and quality, which did not cause much trouble.

The event that really changed the situation in Cambodia occurred in July.

Not only did the peacekeepers bring in more than 2,000 soldiers, but they also brought in a large amount of relief supplies to resettle Cambodian refugees. There are many types of humanitarian relief materials, from basic tents, blankets, clothing, to medicines, drinking water, and food.

Originally, these supplies were well distributed and brought a lot of help to the lives of refugees in Cambodia, but Cambodia is not only the refugees who lack medical care and are malnourished. I don't know if Lu Dao ate the bear's heart and leopard's gall, but when a convoy of humanitarian relief supplies was being delivered to a remote area, the armed forces of the Phnom Penh government and a group of Vietnamese soldiers ransacked the convoy. So the Vietnamese soldiers succeeded in hijacking the convoy, seizing a large amount of food and medicine, and even killing three Cambodian volunteers and a Greek volunteer in the convoy.

After this incident was exposed, it caused an international uproar. The mainstream Western media began to attack the Phnom Penh and Hanoi governments, and even some of the more radical media described the incident as "banditry" as an insulting word and considered it bloody and brutal and must be punished.

UN Secretary-General de Cuéllar strongly condemned the violent acts of looting humanitarian aid and killing people by the Phnom Penh and Vietnamese forces, and said that if the situation develops in a worse direction, more drastic but appropriate measures to protect the lives and property of Cambodians cannot be ruled out.

A spokesman for the Chinese Foreign Ministry said at a regular press conference: "...... We strongly condemn the violent acts of the perpetrators, which can only lead to a worsening of the situation and thus push the Cambodian people into the abyss. China will then submit a draft to the UN Security Council to urgently send more peacekeeping troops to Cambodia, and call on the international community to continue to pay attention to the situation in Cambodia and provide assistance to the best of its ability. ”

The United States has basically expressed its condemnation of Vietnam and Cambodia, but in response to China's intention to send more peacekeeping troops, the White House spokesman said that it does not want to see the use of violence to counter violence, and that the use of force can never finally solve the problem, and hopes that all parties can calm down and return to a negotiated solution.

First, the Hanoi authorities denied that the Vietnamese army was involved in the looting and massacres, and complained that there were people who wanted to frame Vietnam, claiming that Vietnam was a just and upright country, and that the Vietnamese people should not be fooled by the enemy's conspiracy.

Naturally, such an attitude could not solve the problem, so some clashes broke out again between the government forces of Minkhamp and Phnom Penh, and even these clashes even affected the United Nations peacekeeping forces.

I don't know what Lu Dao had in mind, but only a week after the incident, the Vietnamese attacked a humanitarian relief material distribution camp not far from Kampong Son on the outskirts of Kampong Son again, probably because they had grabbed a lot of supplies they were in need of last time, and this time they wanted to get more. In particular, the Vietnamese detected that the peacekeepers had brought a lot of good equipment, and for Vietnam, which lacked elite weapons, it would be a major victory to capture it.

It is this kind of miraculous thinking, completely out of touch with reality, that the Vietnamese army actually took the initiative to attack the peacekeeping forces, perhaps because they have instilled such things as "imperialism" and "aggressor" so badly that they have no sense of reverence for the United Nations.

However, this time the Vietnamese did not fight a transport convoy without escorts, but a material camp under the heavy guard of the peacekeeping forces, and there was a battalion of Chinese blue hats, although there were only more than 300 people, but it had far better equipment than the Vietnamese side.

After discovering that the Vietnamese planned to attack at night, the sentries in the camp sounded the alarm, and the soldiers who were waiting for the day immediately entered the combat state and launched an attack on the Vietnamese who were sneaking over.

The peacekeepers carried a large number of 60 mortars and light and heavy machine guns, while the Vietnamese troops attacking the camp were basically armed with rifles and did not even have decent heavy firepower. It was easy to fire crossfire in the dark of night, and before the Vietnamese could react, they saw several flares being fired into the sky, and then strafing so much that people couldn't lift their heads.
