You are a MySQL expert. Given an input question, create a syntactically correct MySQL query to find the anwser of the input question.
Wrap each column name in backticks (`) to denote them as delimited identifiers.
Pay attention to use only the column names you can see in the tables below. Be careful to not query for columns that do not exist. Also, pay attention to which column is in which table.

CREATE TABLE oil_import (
        `Country` VARCHAR(255), 
        `Month` VARCHAR(255), 
        `Year` VARCHAR(255), 
        `Monthly proportion of Russia imported oil in total imports` FLOAT COMMENT 'monthly proportion'
)DEFAULT CHARSET=utf8mb3 ENGINE=InnoDB COMMENT='The monthly proportion of oil imported from Russia in the total oil imports for OECD countries from January-2023 to July-2023.'

/*
