A North Korean toy company has introduced new building block sets that closely resemble Lego rocket ships and ninjas, in what appears to be the latest example of the country producing knockoff versions of foreign products.

The “Building Blocks” (조립식놀이감) sets by toy manufacturer “Sangmyung” (상명) first appeared on North Korean state television in October, and the North Korean-linked Twitter account @Parama_Coreafan posted close-up images of some of the toys on Sunday.

One set called “Manned Spacecraft” (유인우주비행선) presents a rocket launch scene that closely mirrors the Lego model “Deep Space Rocket and Launch Control,”
