Scientists have discovered a secret war-time passageway under the ground between China and Russia.
The tunnel, carved through rock, is said to have been laid in 1933 and was pivotal combating the Japanese invasion of China by allowing the exchange of intelligence.
It was uncovered following research by a member of staff at China’s Dongning Fortress who was told about its existence during a visit to North Korea a few years ago.
Van Tszunzhen said he met a local expert who let him know Koreans were involved in the construction of the secret pass, 55km from Ussuriysk and 153km from Vladivostok.

He learned it was carved out in November 1933 and played a significant role in the exchange of intelligence between members of the Chinese Resistance and the Soviet Army, following the invasion of Manchuria by the Japanese two years earlier.
After the invasion the Japanese began constructing a series of underground fortresses in preparation for a war against the Soviet Union, and as many as three million slaves were used to build them over an 11 year period.
It is said that more than one million Chinese, Russian and Koreans died in the project, which included the building of the vast Dongning Fortress close to the secret tunnel.
Manchuria was liberated in 1945 by the Soviet army and a memorial has been built within Dongning to commemorate the battle at Mount Shenhunshan – said to be the last battle of the Second World War.
