The two-day meeting will be held in advance of the G20 Hangzhou Summit, which is slated for Sept. 4 and 5. China took over the G20 presidency in December last year.
"Global trade plays a weakened role as an engine for economic growth as its growth loses steam. Therefore, G20 members have a strong will to strengthen trade and investment cooperation," Ministry of Commerce (MOC) spokesperson Shen Danyang said at a press conference.
The G20 Trade and Investment Working Group was established this year based on a proposal from China.
The meetings of trade ministers and the working group will allow G20 members to hold in-depth talks on topics including trade and investment mechanisms, global trade expansion and multilateral trading system development.
