There is no announced time for the signing of the trade agreement between the US and China

Citi discusses the CHF outlook and flags a scope for long USD/CHF and long EUR/CHF to outperform over the coming weeks on the back of the following 4 reasons.
“(i) the SNB will continue to intervene given current levels of EURCHF and USDCHF;
(ii) risk aversion on a US-Iran deescalation should diminish;
(iii) troughing data in Europe will be short-term negative CHF; and
(iv) technical levels and price action make risk/reward attractive,” Citi notes.
As far as I know, China did make a commitment to expand imports from the US. China has a huge market which is growing quickly. It will be more of a test for the US whether it can provide enough products that Chinese market welcomes and are competitive in price.
The US delegation will also comprise of Mnuchin, Ross and Lighthizer. From the EU camp, the notable attendees will be ECB president Lagarde as well as European Commission president von der Leyen.
The nearly $80 billion more worth of US manufactured goods is based off the 2017 baseline figure, according to sources cited by Reuters. Adding that the purchase increase will include autos, auto parts, aircraft, agricultural machinery and medical devices.
