China strongly opposes the proliferation of weapons of mass destruction (WMD) and does not allow any Chinese company or individual to engage in such activities, said Foreign Ministry spokesman Liu Jianchao on Tuesday.

It is reported that the U.S. government is considering imposing sanctions on several small Chinese banks, which have business with companies of the Democratic People's Republic of Korea (DPRK) involved in the proliferation of WMD.

When asked to make comments on this issue, Liu told a regular press conference that the Chinese government holds a firm and definite stance over the non-proliferation issue.

China strongly opposes any Chinese company or individual engaging in activities concerning proliferation of WMD, said the spokesman.

China also maintains that problems in this field should be solved through dialogue not sanctions, Liu noted.
