China produced six new intercontinental ballistic missiles in the first four months of the year, increasing its arsenal by a third, The Washington Times reported Tuesday.

Citing unidentified Pentagon intelligence officials, the paper said it was told China will build two more missiles this year before shutting down and relocating its sole ICBM production plant as part of a major defense industry restructuring."This is missile production far beyond anything we have seen from the Chinese in recent years," the Times quoted one official as saying.

Officials who spoke to the Times on condition of anonymity said the latest intelligence report on China's missiles was based on satellite photographs and other sensitive sources.
