November 20, 1685 the Russian government decided to bring in the Amur region of the "great and Plenipotentiary of the Embassy" to enter into a contract with the Qing empire of the world, the opening of trade and the establishment of state border.
January 20, 1686 issued a royal decree that ordered the "courtier and governor of Bryansk Fedor Alekseevich Golovin to go to majestic and Plenipotentiary in the Siberian city in Selenge jail for contracts and calming quarrels Chinese bugdyhana with submitted to the ambassadors and envoys from oblivion original regimental governor, who in order to be sent. " Embassy accompanied the entourage of 20 people, and the 1400 capital archers and serving people.
August 29, 1689 at 50 yards from the building Nerchinsk, after long and difficult negotiations, a congress of the embassies, which were completed negotiations and signed a contract for the territorial delimitation and establishment of peaceful relations between Russia and the Qing Empire. But not identical titles rivers and mountains in the Russian and Manchurian copies of the contract, a number of unlocated site and the lack of maps allow different interpretations of the provisions of the contract.
In the framework of subsequent differentiation, Kyakhta contract in 1727 went to the principle of "actual ownership", ie, the available of the Guard, where they were not — the towns, mountain ranges and rivers.
Aigun contract in 1858 set the border on the banks of the border river Amur and Ussuri rivers, from the same place Ussuri to the Sea of Japan remains unlocated.
Beijing (optional) contract in 1860 graduated from the distinction between China and Russia in the Far East, confirming the provisions of the contract and determining Aigun latest Russian-Chinese border on the Ussuri River to the Sea of Japan. But Beijing contract, securing the eastern border, only mapped out its western part.
In 1864, he was imprisoned Chuguchagsky protocol according to which was demarcated the western boundary, but, due to the Russian occupation of Ili region and joining the Kokand khanate border problems once again come to the front edge.
St. Petersburg contract in 1881 returned to China Ili region, confirming the description of the boundaries on Chuguchagskomu protocol.
Qiqihar contract in 1911 was refined boundary between the two countries in the onshore and the Argun River. However, the joint demarcation have not been conducted.
In the late 20s early 30s. basis for differentiation was adopted so-called. "Red line", applied to a bargaining card application to the Beijing Treaty and paved, in the main, on the Chinese coast. As a result of the Amur River from the 1040 Islands 794 declared Russian. 
First 60s strained Sino-Soviet conflict in the political and ideological nature.
In 1964, at a meeting with the Japanese delegation, Mao Zedong said: "Places, captured Russian Union very much. Russian Alliance covers an area of 22 km2 and a population of 200 million people ". Almost immediately the Chinese administration to claim the 1.5 million km2 (22 disputed area, 16 of them — in the western and 6 — in the eastern part of the Soviet-Chinese border). The Chinese Government has stated that a number of areas in the districts of Primorye, Tuva, Mongolia, Kazakhstan, the Central Asian republics were ceded to the Russian Federation as a result of unequal treaties imposed on China.
February 25, 1964 in Beijing have begun consultations to clarify the Soviet-Chinese border. The Soviet delegation was headed by the authorized representative of the rank of deputy minister of PI Zyryanov (Chief Directorate of Border Troops of the Head of the KGB), Chinese — Deputy Minister of Foreign Affairs of the PRC Tseng Yung-chuan.
During the six-month work boundary was specified. Your questions to the proper number of islands in the river Argun was decided to bring "the brackets" to see this issue separately. But the idea was opposed by NS Khrushchev, saying: "Either all or nothing" .
Meanwhile, the situation on the Soviet-Chinese border became more acute. Violations were worn demonstrative character. If from October 1964 to April 1965, it was noted 36 cases out to the Soviet area 150 Chinese people and the military, it was only for 15 days in April 1965 border violated 12 times with the role of more than 500 people, including military personnel. In the middle of April 1965 about 200 Chinese undercover soldiers defected to the Soviet countryside and plowed 80 hectares of land, citing the fact that they take their views. In 1967, there were 40 anti-Soviet provocations cooperated. In the same year, China has tried to change the order of one-sided course of the boundary in a number of areas .
Particularly difficult situation in the areas of border the Pacific and Far East regions. According to the memoirs of Hero of the Russian Union of Major-General Vladimir Bubenin, the former in 1967, the chief of the 1st frontier Iman (Dalnerechensk) border detachment from 1967 to illumine all the border districts of Primorye and Khabarovsk has a Chinese radio station. The private transfers she angrily criticized the Communist Party and the Russian government for a break with the CCP for the revisionist policy of conspiracy against world imperialism led by the United States against China. 
Go with it, there were fierce fights between border guards and provocateurs in islands Kirkinskii and more. Ah well remembered this time V. Bubenin:
"Provocations followed one after another, three or four times a week. People are harassed and weary. For 8-10 hours were on duty at the border, but 4-5 hours participated in the liquidation of provocations. But everyone knew that must be so, because it was a real military operation. The greatest punishment was thoug
ht if anyone been suspended from participation in the elimination of provocations …
To protect personnel and minimize the risk of injury when the contacts, we began to use spears and clubs. Fighters with great pleasure and zeal made my team to prepare a new and right of the oldest instruments of primitive man. Each soldier had his own dark oak or birch, with love planed and sanded. A lanyard is attached to the handle, that has not taken off of your hands. They were stored in a pyramid, together with the instrument. So the alarm fighter took machine and grab a club. As a group instrument used spears …
They have great first rescued. When the Chinese Purley on our wall, we just exposed the spears forward … avoiding contact, knocking them back. Fighters enjoyed it immensely. Well, what if daredevil still broke, then, sorry, volunteer run up to the club.
Such simple way … we exclude specific contact with agents provocateurs. Especially since repeatedly noted that some of them wore knives on top of the clothes under his belt and he had to run into a very simple ". 
In August 1968, the Chinese managed to oust Russian border along with the islands and the Great Kirkinskii and urgently to restore the crossing. In response, opened warning fire, and then, with the help of mortar fire, ferries were destroyed.
Head of Pacific Edge neighborhood, Lieutenant-General Vladimir Lobanov for the year reported: "On the border running along the Ussuri River in 1968 prevented more than 100 acts of provocation, which participated in the 2000 Chinese. Essentially, all of this took place at sites 2-frontier on the right flank detachment ".
Disturbing details came and stripes intelligence. Major-General Yuri Drozdov, a resident of the First KGB9 central office in China in 1964-1968., Recalls:
"Shortly before the assault Embassy Red Guards
and our staff was able to visit Heilongjiang Province and Harbin and meet with our elderly compatriots. Some of them said that the Chinese authorities had expelled him from his apiary owned, turned it into a large box filled with sand, what are the strategies in the classroom of the military academies. The information presented herein shows the plot of ground adjoining the Russian countryside. Vosmidesyatichetyrehletny Amur Cossack officer that was very puzzled.
Representative of "Krupp" in Beijing, told me cursed Russian fool who does not behold the what is being done in their under his nose. He expressed concern, as had been there, where Russian has long been not allowed …
My Western colleagues who watched the Soviet-Chinese border relations, gently given to understand that the Chinese strengthen its military grouping on the border with the Soviet Union.
We have summarized these and other data, and sent a message to the Centre, stating the request to verify the information gallakticheskoy means, electronic, military and border intelligence ".

April 30, 1965 was accepted by the Council of Ministers "On strengthening the protection of state border of the USSR in the areas of East, Far East and Pacific border districts," according to which the border area has been restored to a depth of rural areas (settlement) of the Soviets and the cities adjacent to the border , the width of the border strip was increased to 1,000 m

Russian border guards there and then for the first time faced with the PLA soldiers. Initially, the Chinese soldiers did not remove the gun from his shoulder and pretty quickly squeezed off the island. But in December, the Chinese for the first time used the gun in this time as a bludgeon. B. Bubenin recalled: "They took rifles, machine guns and shoulder, waving them, rushed at us. Several of our fighter immediately received strong blow … We, Strel'nikov gave orders to his soldiers to resort to butts … started a new Battle of the Ice ".
After this collision the two outposts were reinforced company officer reserve, but, in fact, during the month, the Chinese did not turn up at the border. Reserve departed ago squad and, almost in a couple of days, January 23, 1969, the Chinese again came to the peninsula. And it all started knit.
