海基会董事长突然辞职，蒋万安则准备访陆，没否认与大陆高层会面

Group 1 - The Taiwan Strait Exchange Foundation (SEF) chairman Wu Fengshan announced his resignation during a significant board meeting, which was preceded by unusual media alerts indicating the importance of the meeting [1][4] - Wu Fengshan's resignation is seen as a response to the leadership of the Democratic Progressive Party (DPP) and may indicate a shift towards appointing a more assertive leader to manage the SEF amid rising tensions in cross-strait relations [1][6] - The current state of the "Cross-Strait Two Meetings" dialogue mechanism is effectively stalled due to the DPP's denial of the "1992 Consensus," which has led to a lack of communication between the two sides [4][10] Group 2 - Despite the resignation and the stalled dialogue mechanism, there are ongoing efforts for cross-strait exchanges, exemplified by Taipei Mayor Jiang Wan'an's preparations to attend the upcoming "Twin Cities Forum" in Shanghai [6][8] - Jiang Wan'an's potential meetings with high-level officials during the forum could signify a willingness to engage in dialogue, contrasting with the DPP's stance [8] - The DPP's actions regarding the SEF leadership may be seen as ineffective in preventing cross-strait exchanges, as the momentum for communication persists regardless of political changes [10]
