Following the resumption of testing in 1987, an analysis of Chinese test yields suggests at least two additional designs:--Two tests in the 200"300 KT range probably involved the warhead for the DF"21/JL"1 proposed in 1986 by Deng Jiaxian and YuMin. Then, in September 1992, China conducted a low yield test that was reported to validate an aspherical primary for a miniaturized nuclear warhead that could arm the DF"31/JL"2. This development probably obviated the DF"21/JL"1 warhead. China announced its intention to complete negotiations on a CTBT "no later than 1996" following the first full scale test of the warhead for the DF"31 in October 1993. Six tests in the 50"150 KT range probably completed validation for the design.
