Taiwan's President Ma Ying-jeou will meet his Chinese counterpart Xi Jinping in Singapore on Saturday - the first ever meeting between leaders of the two sides.
Both said the talks would focus on relations across the Taiwan Straits.
China claims sovereignty over Taiwan and views the island as a breakaway province which will one day be reunited with the mainland.
But ties have improved since President Ma took office in 2008.
The Chinese government threatens to use military force against Taiwan if it ever attempts to gain outright independence.
Taiwanese spokesman Chen Yi-hsin said President Ma's aim was "to promote peace cross the Taiwan Strait and maintain status quo".
