Which one of the following statements about the Missile Technology Control Regime is not correct?

The Missile Technology Control Regime (MTCR) is an informal, voluntary partnership established in 1987 by the G7 countries. Its primary objective is to curb the proliferation of missiles and unmanned aerial vehicles (UAVs) capable of carrying a payload of at least 500 kg over a range of 300 km or more [1]. Statement 3 is correct as China applied for membership in 2004 but was not admitted due to concerns over its export control standards [1]. Statement 4 is incorrect because several countries outside the formal membership voluntarily adhere to the MTCR guidelines. For instance, China agreed to adhere to the guidelines in 1992 despite not being a partner [1]. The regime explicitly encourages unilateral adherence by non-member states to strengthen global non-proliferation norms.
