Kuomintang honorary chairman Wu Poh-hsiung and Hu "will exchange opinions on strengthening peaceful developments in cross-strait ties under the new situation after the signing of pact," the party said in a statement.
Wu, currently in the southern Chinese city of Guangzhou for a trade and cultural forum, will leave for Beijing on Sunday night for a one-day stop in the Chinese capital, it said.
The signing of the pact, by far the most sweeping ever between the two sides, marks the culmination of a Beijing-friendly policy introduced by Taiwanese President Ma Ying-jeou after he assumed power in 2008.
But opponents say the accord will strengthen Beijing's power over the island, marking a first step towards reunification.
China is Taiwan's largest trading partner, its largest investment destination, and now also home to a growing number of Taiwanese people.
Taiwan and China have been governed separately since a civil war in 1949, but Beijing considers the island part of its territory and has vowed to get it back, by force if necessary.
