Stimulus package 'may grow'

China's government may spend another four trillion yuan to stimulate the slowing economy, Sun Mingchun, chief China economist with Nomura International, said at an investment forum on Wednesday.

"We expect that the central government's stimulus package is very likely to grow to seven billion or to eight trillion yuan if the country's economy doesn't rebound as expected," said Sun.

According to Sun, economic data for March and April is the deciding factor as to whether the government increases the stimulus package.
