In an attempt to help set the tone of DPP's cross-strait policy, former Premier Su Jen-chang, a potential contender in the presidential race next year, proposed on Tuesday a concept called "Taiwan consensus," which is based on the party's 1999 document "Resolution on Taiwan's Future," but with an added emphasis on survival strategies.

DPP is about to begin its primary for the upcoming presidential elections. Some likely candicates are planning their own cross-strait discourses.

For example, DPP chairperson Tsai Ing-wen has established a thinktank to formulate cross-strait policies.

Former premier Frank Hsieh mentioned to replace the 92 consensus with the constitutional consensus.

Another former premier Su Jen-chang also tossed the notion of Taiwan consensus when receiving an exclusive interview with print media, asserting to base the DPP's Resolution on Taiwan's Future in 1999 and insist the country's sovereignty.

He proposed the two principles of survival and democracy.

However, some DPP legislators question that the resolution was written 11 years ago and may not be able to cope with the current cross-strait situations.

Earlier when Frank Hsieh proposed to replace the 92 consensus with the consitutional consensus, which has created a stir in the party.

Now Su followed suits to test the water using the Resolution on Taiwan's future.

It takes time to see whether his idea would gain public approval and win the primary in the party.
