China expressed concerns about the tariff hikes imposed by the United States and Russia-related sanctions during a meeting between the two countries' economic working groups in Washington, the Ministry of Finance said on Saturday.

China's Vice-Minister of Finance Liao Min highlighted the potent package of stimulus policies that the world's second largest economy introduced recently during the meeting on Friday, the sixth edition of its kind, with US Treasury Under Secretary Jay Shambaugh, the ministry said in a statement.

The two sides had in-depth, practical and constructive communication on macroeconomic situation and policies of the two countries, their response to global challenges and cooperation to help low-income countries cope with liquidity challenges, as well as the next step of communication arrangements, the ministry said.

Liao, in Washington attending the annual meetings of the International Monetary Fund and the World Bank Group, also held courtesy talks with US Treasury Secretary Janet Yellen after the meeting between the China-US economic working group.
