 In 2004 , Chen was appointed a Minister without Portfolio and spokesperson of the Executive Yuan . Soon after , another proposal to modify pro @-@ independence guidelines was created . Several DPP legislators believed that the change of the national title from " Republic of China " to " Taiwan , " which is one of the ultimate goals of Taiwan 's <unk> campaign and localization movement , was not necessary . Chen also supported the proposal . The proposal was documented in an essay called New Culture Discourse , drafted by DPP legislator Lee Wen @-@ chung of the New Tide faction . After the essay was leaked to the media , many politicians , including Chen , denied being involved in drafting the document . The document was proved too controversial and was attacked within the party as a result , although some members believed that it was only based on the 1999 Resolution on Taiwan 's Future .
