Xi's remarks came as Myanmar's military chief Sen-Gen Min Aung Hlaing called on him.
During their meeting, Xi said the recent Congress of the ruling Communist Party of China (CPC) has adopted a blueprint for China's economic and social reform and development for the years to come.
"It will not only inject great vitality into China's own development, but also bring new opportunities for various countries, including Myanmar, in their cooperation with China," he said.
Hailing the "profound bilateral friendship", Xi called on the two countries to "strengthen strategic communication and accommodate each other's concerns".

Hlaing congratulated Xi on his re-election as the general secretary of the CPC and on the success of the National Congress.
Calling the two countries close neighbours, he said Myanmar appreciates China's help for its national construction and military building over the years, as well as support for its peace process.
China in the past has provided unwavering support for Myanmars military junta over two decades. China also built a USD 7.3 billion deep-water port in Rakhine, which plays a pivotal role in Beijings belt and road trade initiative.
Meanwhile, China also welcomed a pact between Myanmar and Bangladesh to repatriate over six lakh Rohingya refugees who have fled Myanmar' violence hit Rakhine state since August when the military intensified crackdown against alleged militant outfits.
The situation in Rakhine state in Myanmar from where the refugees fled is "clearly alleviating", Geng said.
