BEIJING - China "firmly" opposes the latest nuclear test conducted by the Democratic People's Republic of Korea (DPRK), according to a statement on Wednesday from the Chinese Foreign Ministry.

The ministry made the statement after the DPRK announced Wednesday that it has successfully carried out its first hydrogen bomb test.

China knew nothing about the first H-bomb test of the Democratic People's Republic of Korea before it announced Wednesday that it has successfully done so, Foreign Ministry spokesperson Hua Chunying said.

"The first H-bomb test was successfully conducted in the DPRK at 10:00 on Wednesday," the DPRK's state media KCNA said.
