In modern times, China has lost a large amount of territory in the tohoku region, and the most distressing thing is that there is not a single sea outlet to the Sea of Japan. In 1860, the Sino-Russian Treaty of Beijing was signed, and the Qing government ceded part of the territory between Jilin Province and the Sea of Japan to Tsarist Russia, thus depriving china of its coastline adjacent to the Sea of Japan. Today, the closest place to the Sea of Japan in China is frozen in Jilin, hunchun Tumen Riverside Ofokawa Village and Six Robes. The village of Hokawa is 9.3 miles from the Sea of Japan.

Here you can look at the three countries at a glance, and you can see Russia and North Korea from a high place. The six robes are less than four kilometers away from the Russian Poshet Bay in a straight line, and crossing here is equivalent to reaching the Sea of Japan. In the history of our country, fishermen in the northeast often fished here. In the more than 100 years since the loss of the sea port, can Chinese ships still enter the Sea of Japan from here? Let's take a look.
In 1886, the Qing government signed the Sino-Russian Treaty on the East Boundary of Hunchun with Russia. China has won the right to enter the Tumen River for free access to the Sea of Japan. Hunchun was once a bustling trading town in Northeast Asia. In the early years of the Republic of China, Hunchun County had a wharf, a shipping company, and opened up inland and offshore international routes. The Tumen River often goes to sea, traveling to and from the ports of Momosan and Busan on the coast of the Sea of Japan, and as far as Shanghai, but only 52 years after having the right to go to sea in 1938. Japan, which had already occupied northeastern China, and the Soviet Union engaged in a battle at Zhanggufeng, where Japan was defeated and blockaded the Tumen River Estuary. China was forced to stop its history of overseas trade, and the tide of trade that has lasted more than half a century has come to an end. Until the founding of new China, because of the close relationship with the Soviet Union, the Soviet Union decided to open the Tumen River estuary again and allow Chinese ships to navigate freely, after the outbreak of the Korean War in June 1956.
China used to call it the Whale Sea
The Soviet Union and North Korea built the Tumen River Railway Bridge, which is an eight-hole 60-meter steel bridge, of which only three holes can be used as navigation holes. The bridge is a road and a railway dual-purpose bridge. The water level of the boycott deck is 9.6 meters high, and large ships cannot pass through the bridge. Only smaller fishing vessels can be navigated. In 1964, the first Sino-Soviet boundary negotiations led China to raise the issue of navigation along the Tumen River, hoping to sign a navigation management system. At the same time, the issue was raised to the North Korean side, but it was later shelved due to the breakdown of Sino-Soviet relations. In 1990, with the consent of the Soviet Union and the DPRK, Jilin Province successfully conducted a scientific expedition along the section of the Tumen River into the Hai River.
In 1991, a lot happened in the year, and in May, the Sino-Soviet Boundary Agreement on the Eastern Section was signed, which clearly stipulated that ships flying the flag of the People's Republic of China could navigate freely in the lower reaches of the Tumen River. In June, China successfully conducted the second scientific expedition of the Tumen River into the sea. But at the end of the year, the Soviet Union collapsed, the Russian era began in the Far East, and the power to go to the sea on the Tumen River entered a new cycle. In 1992, the sino-Russian border negotiations on the eastern sector ended, and China restored its right to sea from the Tumen River.
Northeast China is located between the main ports of Japan and South Korea
However, Russia only allows seasonal fishing vessels, not commercial operations. The establishment of diplomatic relations between China and South Korea in the same year caused dissatisfaction in North Korea, and there was a tense atmosphere in this part of the border, coupled with various complicated situations. Only then has all market expeditions and sea activities fallen silent and stagnant. The international relations in Northeast Asia are complex and changeable, and the power to go to sea on the Tumen River is always hovering between the historical and practical grievances of China, the DPRK, and Russia.
In 2008, Jilin Province proposed a plan for the resumption of navigation on the Tumen River, hoping to organize a team through the construction of a port and open up connectivity to the northeast hinterland through the Tumen River And the Sea of Japan. Russia and North Korea have more than a dozen ports near the mouth of the Tumen River, and once China has the right to go to sea, it will reduce China's dependence on their ports. Based on this, many people believe that if we start from the level of national interests, it is basically hopeless for China to build a port on the Tumen River and obtain commercial sea rights.
There are also many people who believe that the lower reaches of the Tumen River have been deposited for 70 years, and that the water level of the Tumen River is obviously different during the abundant and dry periods. In the dry period can not reach the basic traffic conditions, even if a lot of money is invested to dredge, still can not bypass the railway bridge obstruction, can only pass the ship with a small tonnage, the input-output ratio is too low, it is better to borrow russian and North Korean ports. All of the above, I don't know how everyone thinks about it?
