The Executive Yuan is the executive branch of the government of the Republic of China (Taiwan). Under the amended constitution, the head of the Executive Yuan is the Premier who is positioned as the head of government and has the power to appoint members to serve in the cabinet, while the ROC President is the head of state under the semi-presidential system, who can appoint the Premier and nominate the members of the cabinet. The Premier may be removed by a vote of no-confidence by a majority of the Legislative Yuan, after which the President may either remove the Premier or dissolve the Legislative Yuan and initiate a new election for legislators.

A minister without portfolio is a government minister without specific responsibility as head of a government department. The sinecure is particularly common in countries ruled by coalition governments and a cabinet with decision-making authority wherein ministers without portfolio, while they may not head any particular offices or ministries, may still receive a ministerial salary and have the right to cast a vote in cabinet decisions. The office may also exist to give party leaders whose offices would not otherwise enable them to sit in Cabinet.
