The president made the remarks at Halim Perdanakusuma Airport here Sunday, a moment before he left for Kazakhstan to start his seven-day tour which included Poland and Russia.
"Almost all activities in my working visits (to the three countries) will focus on the economic sector, although we will also discuss other agenda," President Yudhoyono said.
According to Yudhoyono, the main objective of his state visit to Kazakhstan is to discuss trade and investment cooperation.
"We will discuss opportunities for Indonesia to do business in the energy field in that country," the head of state said adding that he also had the same hope for his visit to Poland.
In Russia, the president will attend the G20 Summit which will discuss current global economic conditions.
Presidential spokesman Teuku Faizasyah said earlier that the seven-day visit of the President had strategic meaning in the economic field for Indonesia.
His visit to Astana is at the invitation of President Nursultan Nazarbayev and is a return visit of Nazabayev`s tour of Indonesia.
The two presidents will discuss bilateral issues including trade and investment, food and energy security, cultural and education cooperation, presidential spokesman Teuku Faizasyah said earlier.
During Yudhoyono`s stay in Astana, the capital of Kazakhstan, the two countries will sign five memorandums of understanding on economic cooperation, and cooperation in battling terrorism and money laundering, culture and education and diplomat training.
Yudhoyono is also scheduled to meet with Prime Minister Serik Akhmetov and Kazakhs business leaders.
Faizasyah said Kazakshtan is a country in Central Asia which recorded positive economic growth and produced different kinds of agricultural products, particularly wheat and is rich in natural resources, mainly oil and gas.
He said Indonesia was able to develop mutually beneficial cooperation with Kazakhstan in the field of trade, energy and food.
From Kazakhstan, Yudhoyono and his entourage will proceed to Poland at the invitation of Polish President Bronisaw Komorowski.
The visit to Poland will be the third by Indonesian presidents to that country since both nations established diplomatic relations in 1955. The first was made by President Soekarno in 1959 and the second by President Megawati in 2003.
During his stay in Poland, Yudhoyono will hold talks with his Polish counterpart, Prime Minister Donald Tusk, and Senate Chairman Bogdan Borusewicz.
He will discuss bilateral issues with the Polish leaders including cooperation in trade and investment in the mining sector, energy and environment, defense and security issues.
The two countries will sign memorandums of understanding on cooperation in a number of sectors including fishery, agriculture, trade, investment, mining and education.
The two countries will also sign an agreement on visa free visits for holders of official and diplomat passports between the two countries.
His itinerary will end in Russia where he will attend the 8th summit meeting of G-20 in St. Petersburg.
The G-20 summit meeting will discuss a number of issues -- financial stability, sustainable development for all, jobs, investment and trade.
The Indonesian president is expected to arrive back here on September 7.
