How did china and japan react to european explorers/traders?

The behavior of both countries to the European exploration was very different, China was more open to exploration, had friendly behaviors, and opened up to commercial exchange, however not everything was so simple, since at the end everything ended in war. In the case of Japan it was more closed, it feared that its culture and its social stability would be affected by the arrival of Europeans, that is why they decided to limit commercial transactions, and its treatment was not so cordial.
