New Delhi: India’s Neighbouring country China claims to made a defence mechanism to protect its missiles against nuclear attacks, bunker buster bombs like America's GBU-57 and BrahMos missiles with deep dive capabilities.

As per the reports of The "Underground Steel Great Wall" made by China under its thick mountains could be the country's last line of defence in case of potential attacks.

Qian Qihu, recipient of China's highest science and technology award said that the wall is capable of securing te country's strategic arsenal. Qihu also said that it is capable of withstanding potential attacks, including those from future hypersonic weapons.

Underground Steel Great Wall is a series of defence facilities located deep under mountains, the entrances and exits of its facilities are vulnerable..Qian claimed that if other defences, like the strategic missile interception system, anti-missile system and air defense system fail to work, this Wall will be able to hande these attacks.

China's nuclear strategy follows the principle of no first use and requires the nation to have the capability of withstanding a nuclear attack.

Meanwhile, a Pentagon assessment released on Tuesday said that China is to field some of the world's most advanced weapons systems.
