Which country is poorer, Myanmar or Laos? Who has a better relationship with China

Laos is poorer than Myanmar and is one of the 1 poorest countries in the world. No matter how the country changes, Myanmar has maintained a very good relationship with China in the past 6 years. Although China and Myanmar had some twists and turns the year before, Myanmar knew that it could not be separated from China, a huge neighboring country. There are many Chinese in Myanmar, and their influence is great. According to friends who have traveled to Myanmar, many places in Myanmar are very close to Yunnan, China, and it seems that they do not feel the feeling of going abroad. Burmese people are also very friendly to China people.
