On September 28 local time, Chinese Foreign Minister Wang Yi held a meeting in Beijing with North Korea's Foreign Minister, Trai Qingqi.

This is the second time North Korea has sent a high-level representative to visit China in September, and although there are few official announcements, there may be a far-reaching strategic significance behind the talks from the front lines and background.

In particular, a detail revealed in the official on-site photos revealed, it is also a reminder that the issue of the outskirts may have a new breakthrough.

From the photos of the talks, it can be seen that the size of the North Korean delegation to visit China is huge, with up to 11 members present, which shows the high importance of the meeting.

As the current deputy director of the Department of Border and Ocean Affairs of the Ministry of Foreign Affairs of China, Zhao Lijian's responsibilities mainly focus on border affairs and international river management.

Therefore, it can be seen that the talks will involve the issue of the border sea of the Chinese Dynasty, and the issue of the outlet of the Tuman River may be included.

The Tumen River is an international river whose downstream flows through China, North Korea and Russia.

Although China has the right to use the river section, the outlet is located at the Russian-Russian border.The bridge hole on the Russian-Russian railway bridge is too low, hindering the passage of large Chinese ships, which prevented China from entering the Japanese Sea through the Tunas River, limiting the economic development and regional cooperation in the Northeast region.

For many years, China has been hoping to promote the opening of the Tumen River estuary, but due to the attitude of Russia and North Korea and the complicated geopolitical game, there has been no substantial progress on this issue.

For China, this will provide a direct passageway to the Northeast region into the Sea of Japan, promoting regional economic development, while enhancing China¡¯s strategic influence in Northeast Asia.

For North Korea, this may bring more opportunities for economic cooperation and alleviate its domestic economic difficulties.

Russia can also strengthen the economic development of the Far East and consolidate its relations with China and the DPRK through this cooperation.

However, infrastructure issues and political differences remain the main obstacles, the design flaws of the Russian-Russian railway bridge and the differences in the transformation of dominance.

In addition, the North Korean visit may have two purposes.

The first is about the settlement of the return visit, and the second is about the upcoming APEC summit in South Korea.

Earlier, it was speculated that Trump and Kim Jong-un might resume summit diplomacy during the summit, which made the North Korean nuclear issue become the international focus again.

On the other hand, an important topic of the talks could be the exchange of views on the nuclear issue between the two sides in order to avoid information misjudgment during the Qingzhou summit.

Although China and North Korea¡¯s positions on the nuclear issue are not entirely consistent, and China hopes to solve the issue through dialogue, while North Korea hopes to boost negotiations with nuclear capabilities, the two sides share common goals against U.S. power politics and unilateralism.

Judging from the consensus reached by both sides, the future direction of China-DPRK relations deserves attention. Both countries emphasize the need to turn the blueprint planned by leaders into concrete actions. Whether in the economic, military or diplomatic fields, there is a very broad space for cooperation. Especially in the current international situation, how China and the DPRK deal with external pressure through cooperation will become an important factor affecting the situation in Northeast Asia.

As for the fact that there is really a "trick" in the sea? the answers to these questions are worthy of our attention.
