China and France have made (pleasing) progress in the talk.

pleasant
adj.
1.令人愉快的;舒适的
The walk was very pleasant.
那次散步很愉快.
2.讨人喜欢的;和蔼可亲的
The new manager is a pleasant Chinese American.
新任经理是个和气的美籍华人.
pleasing
adj.
1.令人愉快的,讨人喜欢的;使人满意的,合意的
She is most pleasing in manner and appearance.
她的外貌和举止都非常讨人喜欢.
句意应为“中法两国在会谈中取得了令人满意的结果”,而非“令人高兴的结果”.可见用pleasing更为恰当合意.
