Fuel
Left with several questions following AAIB report. The plumbing of the heat exchanger would be interesting, also if there is bypass or if all fuel must flow through this "radiator".
1. The poor thrust result, being virtually equivalent means both engines experienced poor flow as a result of the same fault.
2. Lack of (starvation) or diminished quality (environmental) would have to have been homogeneous, given separate sources (tanks).
3. From the report, there was some quantity of water in the Fuel. Though not excessive, it isn't soluble in Jet, unless itself dissolved in fluid that is in turn soluble in Fuel (eg Alcohol)
4. The delay in "off-throttle" of seven seconds could be related to a slight difference in temperature of the Fuel, due to its source location.
5. The #1, Port engine draws from the Port Main Tank, which in that flight was on the sun side of the A/C, potentially raising Fuel Temp. slightly.

Your suggestion of Gas Chromatography and Mass Spectroscopy is a good one, I'll wager you're not the only one who's thought of it.
I don't think your questions Re; fuel from China are ill advised at all. Contamination can be caused by substances that "improve" the "quality" of Jet, but in certain circumstances may prove disastrous.
