The President has identified proliferation as a primary danger to U.S. security interests. China has contributed to the danger by providing nuclear weapons technology to Pakistan, and other nuclear technology to Iran and Algeria. China has also supplied CSS-2 intermediate range ballistic missiles to Saudi Arabia, Silkworm anti-ship missiles to Iran and Iraq, and ballistic missile technology to Pakistan and perhaps Iran, North Korea and others. China developed the mobile, solid-fuel M-9 and M-11 short range ballistic missiles reportedly with Pakistan, Syria, and Iran as interested buyers.
