In the Philippines, the Securities and Exchange Commission (SEC) raised concerns about Binance. They discovered that Binance wasn't officially registered in the Philippines, so legally, it couldn't sell or offer investments to the public in the country. As a result, accessing Binance might become difficult in the Philippines soon.

However, in Thailand, Binance managed to meet the strict requirements set by the local regulator, the Securities & Exchange Commission. This allowed Binance to establish its exchange in Thailand.

The main thing to understand here is that it's important to follow the rules and laws of each country. Binance succeeded in doing this in Thailand but faced difficulties in the Philippines. That's why Binance chose to open in Thailand instead of the Philippines. It's worth noting that such decisions involve various complex factors.
