DF-41 ICBM: China's answer to American NMD
Aside from building more road- and rail-mobile DF-31As, what's next for China's ICBM program? The obvious answer is the DF-41 with 10 MIRVs.
China's ICBM nuclear forces were quiescent for 20 years until "President George W. Bush formally announced December 13 [2001] that the United States will unilaterally withdraw from the Anti-Ballistic Missile (ABM) Treaty." (See
Withdrawal from ABM treaty signals escalation of US militarism)
The formal withdrawal occurred six months after notification, when "the United States withdrew from the landmark 1972 Anti-Ballistic Missile (ABM) Treaty on June 13 [2002]." (See
U.S. Withdraws From ABM Treaty; Global Response Muted | Arms Control Association)
The Chinese response was swift. China had possessed the basic technology for MIRVs in 1981, but only tested it after the United States withdrew from the ABM treaty in 2002. China's first known successful MIRV test occurred in December 2002, six months after the U.S. withdrawal from the ABM treaty.
To preserve China's security through mutually-assured-destruction, China must maintain a capability to inflict sufficient damage in a counter-strike. Towards that strategic objective, China is building the DF-41 with 10 MIRVs to overwhelm any American National Missile Defense (NMD) shield.
In a counter-strike, for every DF-41 with 10 warheads, the United States must build 10 interceptors. There is also the question of how many interceptors will succeed (e.g. the success rate). I am leaving aside the question of whether the NMD is viable at all. For example, if China attacked the sea-based X-band radar sites then the NMD will be significantly impaired.
Anyway, it will always be far cheaper for China to build DF-41 ICBMs and much more expensive to defend against them. Ten DF-41s with 10 MIRVs each will require 100 interceptors. 100 DF-41s with 10 MIRVs each will require 1,000 interceptors. It is pointless to build a NMD against a near-peer opponent. The other side can easily overwhelm a NMD system.
I will leave it to you to decide whether America was safer prior to President Bush's withdrawal from the ABM treaty. Prior to 2002, China only had 20 DF-5s capable of a counter-strike against the United States. Forced to counter President Bush's NMD initiative, China is on its way to becoming armed with an ever-increasing number of MIRVs.
According to Jane's Defense, China's DF-41 ICBM is capable of carrying 10 MIRVs. (See

Look carefully at the unique double-ring with multiple horizontal bars on the end of the DF-41 canister. It is the same design in both the top and bottom pictures.

DF-41 (CSS-X-10) (China)...
Type
Inter-continental range, road/rail mobile, solid propellant, single warhead or MIRV-capable ballistic missile.
Development
The Chinese are believed to have started the design and development of the Dong Feng-41 (DF-41) in 1986, with the operational requirement to have a solid-propellant, road mobile, ballistic missile with a
range of 12,000 km to replace the CSS-4 (DF-5 and DF-5A) liquid-propellant missiles. The development for DF-41 is believed to be managed by the China Aerospace Sciences and Industry Corporation (CASIC), Beijing (it was the First Academy of the Ministry of Aerospace Industries). The flight test programme is managed by the 2nd Artillery Corps, based at the Wuzhai test centre in Shanxi province. There has been one reported ground test and a simulated cold launch in October 1999, but no test flights to date, although a test was reported to have been in preparation in September 2001. Original reports stated that DF-41 used the first two stages of the DF-31, with a lengthened third stage, but it is now believed that this description referred to the DF-31A, and that the DF-41 is a new design. It is believed that the NATO designator is CSS-X-10. Reports in 1996 suggested that DF-41 would have between two and nine Multiple Independently Targeted Re-entry Vehicle (MIRV) warheads, but it is possible that the initial build missiles will have provision for either a single warhead or
up to 10 MIRV. In 2001 both rail-car and cross-country Transporter-Erector-Launcher (TEL) projects were noted for DF-31, and it is presumed that these might also be adapted later for DF-41. These launchers appeared to use a rail-car."
