Xi said in his report at 19th CPC National Congress in October past year that China was willing to share favorable circumstances regarding China's development with Taiwanese people and would expand economic and cultural exchanges across the Taiwan Strait.
"As to the global order, we have no intention of overthrowing everything for starting over again", Zhang said.
Zhang said China doesn't want a trade war, but wouldn't allow its interests to be harmed.
The man who was master of ceremonies at Hong Kong's handover to China in 1997 stepped into the media spotlight again on Sunday, this time as parliamentary spokesman.
Xi has consolidated power since taking office as party chief in 2012 but the move to lift presidential term limits surprised even the most experienced China watchers.
The annual session of the CPPCC will begin on March 4.
Zhang said that friction in Sino-U.S. trade is unsurprising given the staggering volume of bilateral trade, which stood at $580 billion at the end of a year ago.
Trump believes the tariffs will safeguard American jobs, but many economists say the impact of price increases for users of steel and aluminum, such as the auto and oil industries, will destroy more jobs than curbs on imports create. China has sharply criticized the US move on tariffs, saying it would hurt the global economy.
However, he insisted that cooperation was the only way to resolve those differences, citing the example of Chinese top economic adviser Liu He's visit to Washington this week for a series of meetings with U.S. government officials.
Beijing, Mar 2 Characterising China as a "sharp power" by some western countries is a new version of bias and hype to project "China as threat", a Chinese official said today.
A reason behind China's reluctance to unveil the growth rate of its military budget this year is that it is trying to avoid the further spread of the "China threat theory", foreign affairs experts said.
During the trip, Liu promised a group of US business leaders in Washington that he'd take on oversight of China's financial policy as part of a cabinet reshuffle this month and that he would take steps to reform China's economy, according to a person familiar with the situation. Xi's government has already launched a probe into USA imports of sorghum, and is studying whether to restrict shipments of US soybeans - targets that could hurt Trump's support in some politically important farming states.
Zhang said the right way to deal with trade friction is to have open markets and use dialogue to find a solution that is acceptable for both sides.
Zhang emphasized that trade disputes should be resolved through dialogue. "And Trump is largely not supported by major USA companies".
