I didn't assert anywhere that because they're a member of SWIFT that it "makes it an international bank". However, since you want to debate whether they are or they are not an international bank and you've been rude about it, any person with an iota of common sense would ask themselves these basic questions.
Does this bank have capacity to receive inward remittances from overseas banks? Yes
Does this bank have capacity to send outward remittances in foreign currency? Yes.
Do they allow foreigners to establish a bank account or facilities with them? Yes.
Do they trade in global markets? Yes
Do they offer an international guarantee? Yes
Do they trade in foreign currencies? Yes
Do they offer international L/C's? Yes
Yet here you are arguing whether they are an international bank or not. You are obviously clueless on what a bank is, what their operations are, what their compliance rules are etc. I doubt you have worked in the financial industry, hence your complete ignorance on the subject. I really love it when people like you try and assert their knowledge on something they know nothing about, then they use emojis as some sort of slur as you have done to show that you know nothing on the subject.
One would also wonder why Krung Thai Bank have offices in Singapore, Mumbai, China, Cambodia, Laos, Myanmar, Cayman Islands, since according to you they are "not factually an international bank". I suggest you look into how banks can be sanctioned when they are operating in foreign countries when they don't comply with laws in regard to money laundering, KYC, etc Better not though, since you're clueless about SOP in banking.
Last but not least, according to you "they're not an international bank", one would wonder why they offer the following products, international trade financing services. What would be their purpose of offering international trade finance, since according to you "they're not an international bank".
