Bush tells Hu shipment of warhead fuse to Taiwan a 'mistake'

WASHINGTON (AFP) — US President George W. Bush told his Chinese counterpart Hu Jintao Wednesday that the Pentagon made a "mistake" by sending Taiwan four nuclear warhead fuses in 2006, a top White House official said.

Bush told Hu in a telephone calls "that a mistake had been made," national security advisor Stephen Hadley told reporters.

Hadley said the issue "came up very briefly" and that "there was very little discussion about it."

The erroneous shipment of the fuses, which can be used to trigger warheads on ballistic missiles, was only discovered last week, the Pentagon said on Tuesday.

China on Wednesday expressed "grave concern" over the revelation.

"We express our serious concern and strong dissatisfaction and demand the US side investigate this incident," foreign ministry spokesman Qin Gang said in a statement.

"We urge the US to cease selling military hardware to Taiwan and end US-Taiwan military ties, or risk harming stability in the Taiwan Strait and the healthy and stable development of China-US ties."

Nose cone assemblies containing the fuses were recovered on Monday from Taiwan where they had been held in storage after being shipped there as helicopter batteries, senior Pentagon officials said.

US Defense Secretary Robert Gates has ordered an investigation into the incident and a comprehensive review of the US inventory of all nuclear-related components as well as of policies and procedures, the officials said.
