TAIPEI -- Positive developments in cross-Straits relations have led more international firms to invest in Taiwan in hopes of tapping into mainland and Asian markets, Taiwan leader Ma Ying-jeou said during a business forum on Wednesday.

Closer cross-Strait ties, together with Taiwan's favorable geographical condition, innovative market, human resources and industry clusters, are the key factors attracting international investment, Ma said at the 2014 Taiwan Business Alliance Conference in Taipei.

Investment from overseas surged 29.4 percent from $3.812 billion in 2010 to $4.933 billion in 2013, Ma cited data from the island's economic authority.
