Indonesian President Susilo Bambang Yudhoyono winds up his official visit to Germany on Tuesday with talks with Chancellor Angela Merkel aimed at strengthening the business ties between the two countries. After their meeting, Yudhoyono is to join the German chancellor on a tour of the International travel fair that officially opens in Berlin on Wednesday. Indonesia is the partner country for the world's largest tourism trade fair, according to a report of DPA. The Indonesian leader is also set to meet Berlin Mayor Klaus Wowereit before walking through the German capital's historic Brandenburg Gate. Yudhoyono is scheduled to continue his European trip later on Tuesday when he flies to Budapest for a three-day visit to Hungary aimed at what officials in Jakarta said was reinvigorating Indonesia's relations with one of Central Europe's key states.
