More than 100 million Chinese took foreign trips in 2014 and their overseas consumption surpassed 1 trillion yuan ($159.62 billion), said Gao Hucheng, Minister of Commerce, at a press conference on Saturday.

The main reason for the boom in overseas consumption is the price difference between the domestic and international markets, according to the minister of commerce.

The difference was primarily caused by high taxes and fees, especially the consumption tax on certain products, high cost of domestic circulation and price strategies of foreign brands, Gao added.

China, US complete text negotiation on BIT

Based on the consensus of presidents of the two countries, and after nine rounds of substantive negotiations, China and US have basically completed the text negotiation on Bilateral Investment Treaty (BIT).

Then, early this year, the two sides will change negative lists.

The completion of negotiation and the signing of the China-US BIT will have significant implications on global investment rules, said Gao.

Export growth will turn positive in March

China's export and import will end contraction and usher in a positive growth in March.

The foreign trade in February, based on the analysis of leading indicators, will remain a negative growth, but the decline rate will narrow significantly, said Gao.

Trade in January fell by more than 10 percent, with export sliding by 3.2 percent and imports plunging 19.7 percent, according to data from General Administration of Customs.

The country plans to set this year's target for foreign trade growth to 6 percent from 7.5 percent, announced Premier Li Keqiang in the draft work report.

"Provided a fairly same environment with no significant changes compared to last year, international demand will remain a moderate growth, and we are confident to achieve the target," said Gao.

Apart from non-comparable factors, China's foreign trades grew 6.1 percent in 2014, with export up 8.7 percent, said Gao, adding that the sharp price decline in import commodity was the main reason why last year's target was missed.

Gao said the export growth in 2014 was a satisfactory, given the base of years of 9 percent growth from 2008.

"A fundamental estimate is that until now, we can't see any sign of a quick rebound to the price of resources, energy and bulk farm products," said Gao.
