The Chinese government had been recognized by the international community for 60 years, but when the Republic was first established, it was isolated by the Western society for a long time because of sensitive issues like ideology.
Adding to the fact that China had a weak national strength at that time, the keynote of their diplomacy was mostly based on forbearance and magnanimity. When there was a visit from the so-called 'international friends,' whether it was official or with a separate connection, the Chinese government would welcome and entertain them enthusiastically, with all expenses paid.
