Dear James

As I have informed you already, Kate is in Russia these days. She had a very difficult meeting with the farmers in Y region, relating to the low quality of the potato seeds they had supplied in 2013 and 2014. Later in the evening, we had a phone conversation with Kate and she asked for a meeting in the meeting and to talk over a cup of coffee. She also expressed her hope that I would  return to their company and will continue my cooperation with them. I did not refuse to meet as I have many things to tell her.
James, as I refer to you as to my as I consider you to be a friend and partner, I need your advice.
What do you think if, on September 4-6, you could also invite to the USA 2 or 3 of my ex major? farmers from KTC , besides Anna and Jim ? I think that will be the right thing to do as they have to see for themselves that, besides KTC, there is another trustworthy partner.
If in the fall , in October, some of your varieties will appear to be high -yielding, we will have a firm place in the Russian market.
I am not the one for  building his business on other companies' failures and rejoicing at / taking delight in such things, as failure can happen to anyone.( I don`t accept using the failures of other companies ) .We have to think a lot and consult with each other before taking any step.

I look forward to hearing from you soon.
Best regards,

Good letter.  I didn't know what you meant by "ex major".  Perhaps farmers who used to be large? Check also my punctuation corrrections. Michael
