How mistrust is fuelling a missile arms race between China and the US
The two nations must discuss their anxieties over each other’s increasingly sophisticated weaponry or risk further ratcheting up tensions, writes Ankit Panda

Within the space of a week, the United States and China have tested similar ballistic missile defence systems.
The US Missile Defence Agency, with little publicity, tested a Standard Missile-3 (SM-3) Block IIA variant interceptor at the end of January. The test reportedly failed – the second failure of that interceptor type in a year.
Days later, China reportedly test fired a Dong Neng-3 (DN-3) interceptor from its Korla test site, intercepting a Dong Feng-21 missile over Chinese territory successfully. The Chinese test also came shortly after India carried out the fifth known test of its Agni-V intermediate-range ballistic missile.
China’s indigenous ballistic missile defence capabilities are advancing at breakneck speed.
The fundamental technology Beijing has repeatedly showed with systems like the DN-3 is similar to what the US is endeavouring to accomplish with the SM-3 as well as other systems.
