Huang Kuo-chang, head of the Taiwan People's Party (TPP), wrote an open letter urging the U.S. Congress to formally codify the Six Assurances into law [1].

The move represents a push to transform diplomatic pledges into statutory obligations, potentially altering the legal framework of the security relationship between Washington and Taipei.

Huang directed the appeal to the U.S. Congress, saying that the legal codification of these policies would provide a more stable foundation for Taiwan's security [1]. The Six Assurances [1] are a set of diplomatic commitments dating back to the Reagan era that outline the U.S. position on arms sales, and official relations with Taiwan.

By turning these assurances into binding law, the TPP leader said the U.S. commitment to Taiwan’s international space and security would be strengthened [1]. This approach seeks to remove the ambiguity often associated with executive-branch pledges, which can shift with changing presidential administrations.

The appeal emphasizes that formal legislation would signal a permanent and unwavering resolve from the U.S. government [1]. Such a shift would move the Six Assurances from the realm of policy—which is flexible—to the realm of law, which is rigid and enforceable.

Huang said the request is intended to ensure that the U.S. remains a reliable partner in maintaining stability across the region [1].

Huang Kuo-chang wrote an open letter urging the U.S. Congress to formally codify the Six Assurances into law.

This request highlights a strategic desire within Taiwan's political opposition to move away from 'strategic ambiguity' toward a more explicit, legally binding security guarantee. By urging the U.S. to codify the Six Assurances, the TPP is attempting to insulate the U.S.-Taiwan security relationship from the volatility of U.S. domestic political cycles, though such a move would likely provoke a strong diplomatic response from Beijing.
