After the re-election of Chen Shui-bian in 2004, Hu's government changed the previous blanket no-contact policy, a holdover from the Jiang Zemin administration. Under the new policy, on the one hand, the PRC government continued a no-contact policy towards Chen Shui-bian. It maintained its military build-up against Taiwan, and pursued a vigorous policy of isolating Taiwan diplomatically. In March 2005, the Anti-Secession Law was passed by the National People's Congress, formalizing "non-peaceful means" as an option of response to a formal declaration of independence in Taiwan.
