Re “Tracing Success of North Korea to Ukraine Plant” (front page, Aug. 14): I was alarmed by suggestions in your article that Ukraine may have supplied rocket technology to North Korea. The article suggests that North Korea has been using an engine called the RD-250, then confirmed that the RD-250 was developed in Russia, and then made the leap that the technology leakage came from Ukraine. But no evidence has been provided to support the claims.
As Ukraine’s foreign minister and a trained aerophysicist, I want to say that my country could not have been involved in aiding North Korea’s missile program.
