Port-of-Spain - President Goodluck Jonathan is visiting Trinidad and Tobago for the Caribbean nation's Emancipation Day holiday.
The president told attendees at Wednesday's parade in Port-of-Spain that strong ancestral links bind the two energy-rich countries.
Wearing his signature black bowler hat, Jonathan walked beside Prime Minister Kamla Persad-Bissessar until a downpour sent people scurrying for shelter.
Trinidad, Jamaica and other Caribbean nations mark Emancipation Day on 1 August. That's when the British slave trade ended in 1834. People commemorate the day with the playing of African music and the wearing of traditional African garb.
The Nigerian leader and his wife, Patience, are accompanying a roughly 70-member delegation of government officials and businessmen. The group is due to arrive in Jamaica's capital of Kingston on Thursday.
