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 Chinas 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.
